(Hardy-Weinberg.) Suppose that a particular gene occurs as one of two alleles (A and a), where allele A has frequency 0 € (0, 1) in the population. That is, a random copy of the gene is A with probability and a with probability 1-0. Since a diploid genotype consists of two genes, the probability of each genotype is given by: genotype AA Aa aa probability ² 20(1 – 0) (1 – 0)² Suppose we test a random sample of people and find that n₁ are AA, n₂ are Aa, and n are aa. Find the maximum likelihood estimator ên. Make sure to verify that it is indeed maximizing, by computing the second derivative of the function you are maximizing.

(Hardy-Weinberg.) Suppose that a particular gene occurs as one
of two alleles (A and a), where allele A has frequency 0 (0, 1) in the population. That is, a
random copy of the gene is A with probability and a with probability 1-0. Since a diploid
genotype consists of two genes, the probability of each genotype is given by:
genotype AA
Aa
aa
probability 0² 20(1-0) (1 - 0)²
Suppose we test a random sample of people and find that n₁ are AA, n₂ are Aa, and n
are aa. Find the maximum likelihood estimator ên. Make sure to verify that it is indeed
maximizing, by computing the second derivative of the function you are maximizing.
