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

scoray [572]

Answer: a line connecting her mother and father, a colored circle representing Jenna, and two empty circles representing her sisters

Explanation: Jenna's red hair can be determined by incomplete dominance.

Incomplete dominance is a condition where neither of the alleles responsible for a trait is dominant.

In incomplete dominance, one allele for a specific trait is not completely expressed over its paired allele. So, if an organism is heterozygous for a trait, it shows a third phenotype.
