A study is done on a group of families in Sweden that are segregating a genetic disorder. A statistical estimate of whether two genes, or a gene and a disease gene, are likely to be located near each other on a chromosome (called Lod-score analysis) indicates that the gene involved in the disorder shows a strong likelihood of linkage with a particular DNA marker locus. However, a second study done in Italy with other families segregating the same genetic disorder results in lod-score values that strongly indicate the lack of linkage between the gene and the same DNA marker locus. Assuming that both studies were performed appropriately, what is the most likely explanation for the different outcomes

Answers

Answer 1

Answer:

This disorder is caused by mutations in either of two different genes; one of these genes is linked to the DNA marker locus and the other gene is not.

Explanation:

A gene marker (also known as a molecular marker) is defined as a particular DNA sequence that has a specific physical location on a given chromosome. The gene markers are always physically linked with genes of interest, thereby they are useful for identifying patients affected by a given disease and/or a particular phenotypic trait. In this case, in the first study, genetic variation of the marker has been shown to be useful to map one locus that is associated with the disease phenotype. However, in the second study, a second locus that is not linked to the marker can segregate independently, thereby showing different results from the first study (in this case, it is imperative to develop a new genetic linkage analysis to discover genetic markers linked to the second gene, which is also responsible for the disease phenotype).

2) ¿Cuál de los siguientes hechos no es una evidencia de una reacción química? a) Presencia de un catalizador b) Cambio de color d) Liberación de gas​

Answers

Answer:

a) Presencia de un catalizador

Explanation:

Los dos tipos de cambios que experimentan las sustancias en la química son cambios químicos y físicos.

Un cambio físico es un cambio es un cambio en el que la sustancia cambia en su apariencia o su forma de una manera que es reversible y en la que no se forma una nueva sustancia.

Un cambio químico es aquel en el que hay un cambio en las sustancias presentes y se forma una nueva sustancia.

La evidencia de que ha tenido lugar un cambio químico incluye

1) La formación de un precipitado a partir de la mezcla de sustancias.

2) Un cambio en el color de las sustancias.

3) Un cambio en el olfato (que desprende un olor) o en el sabor.

4) La sustancia produce luz (brilla)

5) El volumen total cambia

6) Cambio de temperatura (la mezcla se calienta o enfría)

Por lo tanto, la presencia de un catalizador, que es una sustancia que no participa en una reacción pero aumenta la velocidad de reacción, no es evidencia de una reacción química.

A zombie apocalypse wipes out almost the entire human species before the zombie threat is eliminated. It appears that only a group of 100 people who were at a family reunion on an uninhabited island survived. They returned to the mainland completely unaware of what had happened to everyone. Answer the following questions regarding the few survivors that now begin to rebuild the human population.

Certain traits will have been lost from the gene pool forever. Some may be obvious, like people with red hair and double jointed thumbs. Others will be less obvious, like the ability to process cholesterol or being allergic to peanuts.

a.) Which of the following best describes the mechanism of microevolution that has altered the human gene pool? Explain.

b.) Despite an abundance of habitat, why will it be difficult for the human species to recover in numbers?

c.) A straggler with green eyes stumbles into the last remaining human outpost. The green eye trait did not exist in the outpost before her arrival, but it does now. What is the name of this mechanism of evolution? Explain.

Answers

Answer and Explanation:

A. Hello. You did not enter answer options. However, we can state that mutation, natural selection and genetic drift will be the microevolution mechanisms that will affect the gene pool of these humans. This is because the new environment and the small number of living beings, will make this population completely susceptible to all these evolutionary factors, which will affect, in different ways, the gene frequencies in a population.

B. As the amount of living beings and human beings has become very small, the world will have a low genetic diversity. This will make it difficult for these humans to adapt to the new environment and will make them more susceptible to possible diseases that will arise in this new environment. This will make these humans more fragile and make it harder for them to multiply.

C. The evolution mechanism is the Gene Flow. Gene Flow refers to the exchange of genetic information between individuals in a population, through the donation of gametes that occur in reproductive processes. In this case, we can consider that the individual with green eyes, upon arriving in the community with individuals without green eyes, began to reproduce descendants, who, upon receiving the gametes responsible for green eyes, began to populate this community with this characteristic.

How do animals and people cause weathering?

How do plants cause weathering ?

Answers

Answer:

Plants can cause mechanical and chemical weathering

Explanation:

Plants can cause mechanical and chemical weathering. When plants cause mechanical weathering, their roots grow into rocks and crack them.It can also happen in streets or sidewalks. When plants cause chemical weathering, there roots release acid or other chemicals, onto rocks, which then forms cracks, and breaks apart.

Animal and plant mobility is a factor in biological weathering, for instance, a plant may grow in a gap in a rock and, as its roots spread, cause the fracture to expand.

What is the cause of weathering?

A rabbit may also burrow into a crack in a rock, making it wider and eventually separating the rock.

Animals and plants can act as mechanical weathering agents. In dirt that has gathered in fractured rock, a tree seed may emerge. The fissures get wider as the roots spread out, finally shattering the rock into pieces.

Even big rocks might get dislodged by trees over time, rocks are broken down by plants like moss that absorb their minerals.

Therefore, holding onto soil and rocks is another way that plant roots cause weathering, and might stop erosion.
