A fruit fly population has a gene with two alleles, A1 and A2. Tests show that 70% of the gametes produced in the population con
IceJOKER [234]

Answer:

Option C

Explanation:

Given ,

A1 allele is carried by 70 % people

Let us assume A1 s dominant genotype

This means p= \frac{70}{100} = 0.7

Thus, frequency of allele in the given population is 0.7

It is also given that the population is in Hardy-Weinberg equilibrium thus

p+q=1\\0.7+q=1\\q = 1-0.7\\q= 0.3

Frequency of fruit fly with genotype A2A2 will be

q^2\\= (0.3)^2\\= 0.09

As per Hardy-Weinberg's second equation of equilibrium

p^{2} + q^{2} + 2pq = 1\\0.49+0.09+2pq = 1\\2pq = 1-0.49-0.09\\2pq= 0.42

Hence, option C is correct

Since humans reproduce then grow and our population grows, does our planet Earth gain mass little by little?
zheka24 [161]
Yes, it does, but not the way people think. it doesn't gain it from the weight of all the people. the earth takes mass from elsewhere, as our population continues to grow.

garik1379 [7]

Answer:

There are numerous biology questions which can arise on the topic of cells.

<em>One of the question can be, 'Do plant cells respond to light?'</em>

A biology inquiry question is a question which arises in the mind of a person by observing some natural phenomenon. To answer the question, a hypothesis is formed which is a tentative statement which might or might not be supported through experiments. The results from the experiments form conclusion for answering the question.
