Answer:

1) Crossing over

2) Independent assortment.

Explanation:

Gametes are formed resulting from the process of meiosis where the gametes get half of the original number of chromosomes. One phenomenon that happens during the prophase 1 of Meiosis and leads to the genetic diversification is crossing over. In this process , Here, homologous chromosomes pair up and exchange information present on genes from one another. When information is exchanged, it leads to the diversity of genetic data.

The second way of increasing genetic diversity is independent assortment that takes place during metaphase 1. In this process chromosomes from both father and mother cells align on equatorial plate of the cell in an independent manner. This means that some gamete can have 1 of many different chromosomal combinations.

This reshuffling of chromosomes during independent assortment enhances the genetic diversity of any organism and this also explains why kids of same parents can look or behave very different.

Hope it help!

What class of mutations do you think would be less likely to lead to cf? explain your reasoning

BabaBlast [244]

Class IV and Class V mutations would be less likely to lead to Cystic Fibrosis (CF).

Class IV mutation or Conduction mutation involves reduced chloride conductance. It changes the shape of the protein channel so that chloride cannot move easily in and out of the cells. Less than 3% of people with cystic fibrosis in Europe have this type of mutation.

Class V or Insufficient Protein mutation is associated with reduced protein levels. It results in a reduction in the amount of CFTR protein produced by the cells. Less than 3% of people with cystic fibrosis in Europe have this type of mutation.

These two classes of mutations cause a milder reduction in CFTR function.

In separate marshes, small populations of three species occur: grass fish, which disperse only in extreme rains and have an aver

Volgvan

The question is incomplete as it does not have the option which are:

a. Grass fish, since they have the least gene flow, and gene flow acts to decrease genetic variation among populations.

b. Swamp rats, since they will have the best balance between genetic drift and gene flow, resulting in high genetic variation among populations.

c. Grass fish, since they are the best adapted to their aquatic environment, and adaptation increases genetic variation among populations.

d. Marsh birds, since they have the highest level of gene flow, and gene flow increases genetic variation among populations.

e. It is not possible to compare relative amounts of genetic variation among such different kinds of animals.

Answer:

Option-A

Explanation:

The genetic variations are introduced in a population when the new combination of gene interact with each other and again a new combination of genes are formed.

This genetic variation is possible when the flow of gene takes place that is the individuals are dispersed to another place.

In the given population, since it has been mentioned that the gene flow of Grass fish was very low because the probability of gene flow was 1 out of 45. Thus, the gene flow was very less, therefore, the less genetic variation is introduced in population.

Thus, Option-A is correct.
