In sweet pea plants, purple flower color is dominant over red flower color and long pollen grain shape is dominant over round pollen grain shape. Two sweet pea plants that we heterozygous for both flower color and pollen grain shape are crossed with one another. A geneticistis surprised to observe that there are fewer round purple offspring and long red offspring than were predicted by the 9:3:3:1 expected phenotypie ratio Which of the following statements provides the most reasonable prediction to account for the deviation from the expected results?
A) in sweet pea plants, the gene for flower color and the gene for pollen grain shape are genetically linked
B) In sweet pea plants the genes for flower color and for pollen grain shape both exhibit codominance
C) Several mutations occurred spontaneously producing a deviation from the expected phenotypic ratio of the offspring
D) The genes for flower color and pollen grain shape are inherited independently because of the law of independent assortment

Answers

Answer:

The correct answer is - option A) in sweet pea plants, the gene for flower color and the gene for pollen grain shape are genetically linked.

Explanation:

In this given case the result of phenotypes are not as expected and does not follow the law of independent assortment presented by Mendel. It appears to be the case of genetic linkage as it is not following the mendelian law by producing fewer round purple offspring and long red offspring which do not satisfy the expected mendelian ratio of 9:3:3:1. Mutation can lead to failure in producing proteins but could not affect the phenotypic ratio of the plant.

Thus, the correct answer is - option A.

Medel was the Father of Genetics, who gave the laws on independent assortment, dominance, and segregation of the genes.

However, there are some exception that violates these laws, such as genetic linkage is one of the exceptions that violates the law of independent assortment.

The correct answer is:

Option A. in sweet pea plants, the gene for flower color and the gene for pollen grain shape are genetically linked

In the given data, the results can be interpreted as:

The Law of independent assortment states that the two or more alleles of different genes are assorted independently.

In the given example, the genetic linkage occurs, which does not follow the ratio of 9:3:3:1. The genetic linkage does not follow the law of independent assortment, which results in fewer purple offspring.

Thus, mutation can cause the failure of Mendel laws and can affect the phenotypic traits of an organism.

Therefore, Option A is correct.

What would you look for under a microscope on a slide with meiotic cells if you wanted to identify metaphase I

Answers

Answer:

This question lacks options, options are: A) A visible nuclear envelope B) Separated sister chromatids at each pole of the cell C) Tetrads lined up at the center of the cell D) A synaptonemal complex E) A cleavage furrow. The correct answer is C.

Explanation:

During Metaphase I, the chromosomes line up at the midpoint or equator between the poles of the cell and are found at their thickest and shortest structure, that is, the tetrads line up at the equator of the cell. They are identified as two double longitudinal sister chromatids. In animals and plants, the chromatids are connected (at their centromeres) to the fusiform apparatus, which has formed between the two centrioles located at the poles of the cell. In many plants, the centrioles are absent. However, the spindle is still present and the plant chromosomes are attached similarly to the microtubule fibers of the spindle.

A) The financial costs for the farmer would be lowered since LESS crops would be lost to pests.

B)The financial costs for the farmer would be lowered since MORE crops would be lost to pests.

C) The farmer may be held responsible for increasing chemical pollution.

D) The farmer's expenses for pest control would increase due to an increase in bee population.

Answers

Answer:

A) The financial costs for the farmer would be lowered since LESS crops would be lost to pests.

Explanation:

Planting of variety with a resistance strain to pest is one of the gene modification that occurs in plants, this has greatly help farmers improve on productivity, reducing the amount of money spent on controlling insect pest invasion on their farm.

Because the crop is resistant to pest no extra cost of purchasing chemicals to control pest on the farm and the number of damage to crop will be reduce in turn reducing the amount of plant lost to pest invasion this will lower the financial cost of the farmer and also an increase productivity.

The diploid number of chromosomes in the mustard plant, Arabidopsis thaliana, is 10. Knowing this, answer the following questions about the stages of mitosis. Part APart complete How many chromosomes will be found in each cell during prophase

Answers

Answer:

10 chromosomes

Explanation:

Ten (10) chromosomes would be found in each cell of Arabidopsis thaliana during prophase.

The prophase stage represents the first stage of the mitotic division immediately after the interphase. A diploid cell has 2n number of chromosomes and the ploidy level of a cell remains intact throughout the interphase to the prophase stage of mitosis.

At the prophase, the chromosomes of a cell only condense and become visible under the microscope. Each chromosome is seen as being consisting of two sister chromatids joined together by a structure known as the centromere.

Hence, the number of chromosomes in the cells of Arabidopsis thaliana would remain the same even at the prophase stage of mitosis.

Why is it possible to do the following party tricks without cheating?
A. Stand with back and heels touching a wall and bend forward from the hips to touch the floor. Return to the upright position without flling or moving the root.
B. Stand facing the edge of an open door with nose and abdomen touching the edge, the feetstraddling the door, and the hands to the sides. Attempt to rise up on the toes.Observe what body motions occur to keep the center of gravity within the base of support whenthese activities are performed without the impediments.

Answers

Answer:

When the body is supported by a wall then it can move in a position counter gravity. The gravity tries to pull the body down and the body responds to it with a slight delay because of wall support.

Explanation:

The body is lifted in upright position with the help of feet. The body rises but after few minutes the gravitational force creates pressure on the body and the body comes down to a natural state. Similarly if the open door is used to perform counter gravity activities then the body will stay for a lesser period in a state because of opened door instead of firm wall support.
