What are the estimated allele frequencies in a population if the frequency of the dominant phenotype is 0.64 (Hint: handout to g
Nadya [2.5K]

Answer:

0.8 and 0.2

Explanation:

Hardy Weinberg law states that the allele frequency of the population remain stable from one generation to next generation if no natural selection, drift or mutation occurs in the population.

Let p and q be the dominant and recessive frequency of the population respectively.

The dominant phenotype means p² = 0.64

p = 0.8

and we known that p + q = 1, in hardy Weinberg equilibrium.

0.8 + q = 1.

q = 0.2

Thus, the dominant allele is 0.8 and recessive allele is 0.2.

lesantik [10]

Answer:

The correct answer is A) Histone deacetylation generally decreases gene expression.

Explanation:

Histones are the proteins that are responsible for the condensation of chromatin, which is directly linked to the capacity that a gene has to be expressed. The more condensed a gene is, the less expressible it becomes.

In order to regulate the gene expression, histones can suffer from many modifications that can change their conformation and the expressiveness of specific genes.

<u>Histone acetylation is linked with an increase of gene expression; while deacetylation and methylation decrease gene expression.</u>

erica [24]

Answer:

The answer is A.

Explanation:

The inner ear parts are responsible for one of the most important sensory responsibilities in our body which is the keep us in balance and provide us with a sense of stability. It is made of three parts named semicircular canals, vestibule and cochlea.

The structure that contains the receptors mentioned in the question and helps us with our head movements to keep our heads horizontally and vertically in the correct position is called "The Saccule" and it is a part of the vestibule part of the inner ear.

I hope this answer helps.
