Answer:

First thing is that word “autonomous” given in the question is actually “ autosomal”.

Now let's start solution:

Frequency of dominant allele “A” is denoted by p.

Here p = 0.6

Frequency of recessive allele “a” is denoted by q.

According to Hardy - Weinberg equilibrium

p + q = 1

Hence q = 1 - p = 1 - 0.6 = 0.4

Now in question what is asked is about frequency of recessive phenotype (aa).

According to Hardy - Wienberg equilibrium frequency of recessive phenotype is q2 (q square).

Frequency of recessive phenotype is = q2 = 0.4 x 0.4 = 0.16

Now Number of recessive phenotype in a population of 10000 is

= frequency of recessive phenotype x total population

= q2 x 10000

= 0.16 x 10000

= 1600

I answer you other question.

I apologize. it's mistakenly
