Suppose that an allele is present in pelican offspring that causes a nestling to share its food with its nestmate if it is not particularly hungry. this gene imposes a fitness cost of 0.2 on those who carry it, while conferring a benefit of 0.5 on the sibling who receives the additional food. will this gene increase in frequency if two nestmates are always full siblings?

Here are the options to the question to make it a complete question

a. No, because rb - c > 0

b. Yes, because rb - c > 0

c. Yes, because rb - c < 0

d. No, because rb - c < 0

The ANSWER IS b.

b. Yes, because rb - c > 0

Explanation:

If Relatedness(r) * Benefit(b)

> Cost(c), an allele will increase. (Hamilton's Rule)

Given:

Cost: 0.2

Benefit: 0.5

Full Sibling Relatedness = 0. 5

0.5 * 0.5 = 0.25.

0.25 > 0.2, should increase.

Hamilton's Rule states that:

Natural selection will favor individuals that help their kin when relatedness(r)is high, benefit(r) to the recipient is also high, and cost (c) to the actor is low,

your answer is "the 1950's"

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects
