inherited genetic variations are caused and influenced by environmental factors only

Answers

Answer:

False, it can also be caused by mutations.

False. Inherited variations come from mutations, independent assortment, crossing over, and fertilization

a) An F1 x F1 self-fertilization gives a 9:7 phenotypic ratio in the F2. What phenotypic ratio would you expect if you test-crossed the F1?

b) An F1 x F1 self-fertilization gives a 9:3:4 phenotypic ratio in the F2. What phenotypic ratio would you expect if you test-crossed the F1?


c) An F1 x F1 self-fertilization gives a 15:1 phenotypic ratio in the F2. What phenotypic ratio would you expect if you test-crossed the F1?

Answers

According to the gene interaction that is operating in the trait determination, the phenotypic ratios of the progeny produced when test-crossing a dihybrid are: a) 4:12, b) 8:8, and c) 12:4

-------------------------

To answer these questions, the first thing you should notice by looking at the phenotypic ratios provided, is that there are two genes involved in the trait, and there is interaction between them.

Let us assume diallelic genes. A and B are the dominant alleles, while a and b are the recessive alleles.

In the three cases (a, b, and c), F1 individuals are dihybrid. Their genotype is AaBb.

Observing the altered phenotype proportions of the offspring can reveal which interaction is operating in the trait determination.

We can use the phenotypic ratio to determine the interaction, so:

9:3:3:1   ⇒   No interaction9:7        ⇒    Double Recessive epistasis 9:3:4     ⇒    Recessive epistasis15:1        ⇒    Dominant duplicate genes.

When talking about epistasis, we are referring to an interruption.

The epistatic gene can alter, influence, or suppress the expression of a hypostatic gene.

When there is only one epistatic gene in h0m0zyg0us recessive state, the interaction is known as recessive epistasis. This gene supresses the expression of the other gene. Phenotypic ratio 9:3:4.

In double recessive epistasis, both genes are epistatic when they are in a h0m0zyg0us recessive state. This is, in the h0m0zyg0us recessive state, either of the genes will inhibit the expression of the other gene. And vice-versa. Phenotypic ratio 9:7.

In Duplicate gene action, there are two genes involved in the expression of a phenotype, and the presence of at least one dominant allele is enough to produce the dominant phenotype. Phenotypic ratio 15:1.

So now, let us make the test-cross.

Note: You will see that the cross is the same in the three cases, but the phenotypic ratio changes according to the interaction.

Cross) dihybrid individual with h0m0zyg0us recessive one

Parental)           AaBb            x          aabb

Gametes)  AB, Ab, aB, ab             ab, ab, ab, ab

Punnett square)     AB            Ab            aB            ab

                 ab       AaBb        Aabb        aaBb        aabb

                 ab       AaBb        Aabb        aaBb        aabb  

                 ab       AaBb        Aabb        aaBb        aabb

                 ab       AaBb        Aabb        aaBb        aabb

F2) Phenotypic ratio

***Double recessive epistasis  ⇒  4:12

4/16 dihybrids12/16 heter0zyg0us for one gene and h0m0zyg0us recessive for the other gene.

Both genes in recessive state inhibit the expression of the trait.

***Recessive epistasis  ⇒  8:8

In h0m0zyg0us recessive state, Gene A inhibits the expression of B.

8/16 AaBb or Aabb → The trait coded by B or b is being expressed8/16 aaBb or aabb → The trait coded by B or b is inhibited by aa.

***Duplicate gene action   ⇒  12:4

Only one dominant allele, either A or B, is enough to express the trait.

12/16 AbBb, Aabb, or aaBb   4/16 aabb → No dominant allele, no trait expressed.

Phenotypic ratios:

a) 4:12 = 1:3

b) 8:8 = 1:1

c) 12:4 = 3:1

Hormones perform important functions within the reproductive system. During puberty, secondary sex characteristics develop. Which hormone is responsible for the development of these characteristics in the female? estrogen progestin progesterone testosterone.

Answers

Answer:

Estrogen

Explanation:

Estrogens are a group of hormones that play an important role in the normal sexual and reproductive development in women.

Estrogen is responsible for the development of these characteristics in the female. Therefore, option (A) is correct.

What is Estrogen?

Estrogen, also known as oestrogen, is a class of sex hormone that is responsible for the growth and regulation of the female reproductive system as well as secondary sex characteristics. Estrone, estradiol, and estriol are the three primary endogenous estrogens that are responsible for the majority of the hormone activity associated with estrogen.

The growth, development, and physiological functioning of the human reproductive system are all controlled by estrogen. In addition to affecting the neuroendocrine and skeletal systems, this hormone also affects the adipose and cardiovascular systems. Estrogen is a vital component of the male and female reproductive systems and is primarily manufactured by the ovaries in females and the testes in males.

According to urban anomie theory the impersonal nature of city life extends to situations that do not call for social involvement. Please select the best answer from the choices provided T F.

Answers

Answer:False

Explanation: right on Edge

The statement "According to urban anomie theory, the impersonal nature of city life extends to situations that do not call for social involvement" is true, as urban anomie theory suggests that the impersonal nature of city life leads to the breakdown of social bonds.

What is urban anomie theory?

According to this theory, the fast pace of urban life, the diversity of populations, and the emphasis on individual achievement can lead to a weakening of social ties and a breakdown of social norms and values. As a result, individuals may feel disconnected from others and from society as a whole, leading to a sense of alienation and a lack of meaning in their lives. This sense of normlessness and detachment can extend beyond situations that require social involvement, such as interactions with neighbors or participation in community events, to other aspects of daily life.

Hence, the statement "According to urban anomie theory, the impersonal nature of city life extends to situations that do not call for social involvement" is true.

Answers

Answer:

The lights higher on the light spectrum, like blue would have the fastest rate of photosynthesis because the energy is the highest. the green light would have the slowest rate because the chlorophyll inside of the leaves reflects green light, so it would not be absorbed as mich as the other colors. The color matters because the color or wavelength of light does affect photosynthesis, which is how plants can create their own food.

Which of the following statements best compares reproduction in viruses with reproduction in single-celled protists? no links please​

Answers

Viruses require the cellular machinery of host cells to reproduce; single-celled protists reproduce on their own. Therefore, the correct option is (C).

Viruses require the cellular machinery of host cells to reproduce; single-celled protists reproduce on their own. The main difference between reproduction in viruses and single-celled protists lies in their reproductive processes. Viruses are obligate intracellular parasites that lack the cellular machinery required for replication. They rely on infecting host cells and hijacking their machinery to reproduce and create new viral particles. In contrast, single-celled protists are independent organisms capable of self-replication through various mechanisms such as binary fission, budding, or spore formation. They do not need a host cell for their reproductive processes. This fundamental distinction highlights the unique strategies employed by viruses and protists in propagating their species.

Therefore, the correct option is (C).

In the 1800s, the United States was still a very young nation, trying to solidify its identity. The Industrial Revolution began in Great Britain, a fast development of society following the introduction of machines. The United States was slower than Great Britain to fully embrace the changes. Yet key technological developments caused a rapid growth in American urban areas.Better farming methods and tools in the 1800s increased food production. Americans were able to grow enough food for their families as well as to sell. The abundance caused food prices to fall.The expansion of cotton and the growth of textile factories in northern states helped produce the first wave of American industry. More people turned to work in northern factories as a way to support their families. Thousands of immigrants to the United States also settled in or near port cities, looking for work. Even today, the need for work is a common reason people move to urban areas.As a result, cities grew in numbers of people and physical space. As more people and businesses moved in, they needed buildings for living and working. They needed ways to move around the city. We call this process urbanization.In 1820, the United States had only a few cities of 10,000 residents or more. About seven percent of U.S. residents lived in urban areas. The number of cities with more than 10,000 people grew quickly over the next 40 years, especially in the Northeast and Midwest. By 1860, about 20 percent lived in cities. Philadelphia and New York City were the most populated cities in 1860 and would soon reach one million residents.The urbanization of the United States quickened due to technology improvements. Without innovations in food production, the factories could not have grown so quickly. The trend quickened after 1860 and continued throughout the 21st century as well. By 2007, more Americans lived in or near cities than they did in rural areas.Select a sentence from the body of this article that can be removed without affecting the author's explanation.
