Answer 4

Which do you think it is? Why or why not? It would be easier to tutor you if you explained what about the question is giving you trouble.

Answer 5

In order to make u understand this i'll work out an other example related to this question !

Answer 6

\(\bf Formulas~Used\)
\(\bullet\) P+Q =1
\(\bullet\) and \[P ^{2}+2PQ+Q ^{2}=1\]

Answer 7

Here,
P=frequency of A
Q=frequency of a
2PQ = frequency of Aa

Answer 8

Now let's see an example
\(\color{red}{\text{In a random population frequency of recessive phenotype is 0.09.}}\)\(\color{red}{\text{What is the frequency of heterozygous genotype ?}}\)

Answer 9

\(\huge\color{blue}{\text{Solution}}\)
Let the recessive allele be a and dominant trait be A.
Now frequency of a recessive phenotype = 0.09 i.e frequency of aa = 0.09.

Answer 10

This implies that frequency of a = \(\sqrt{0.09}\) = 0.03
Now using the formula P+Q = 1, we get that frequency of A = 1-0.03 = 0.7

Answer 11

Frequency of heterozygote i.e Aa = 2PQ = 2*0.7*0.03 = 0.42

Answer 12

This means in a population of 100 individuals, 42 will have a genotype of Aa

Answer 13

You can workout ur question in same manner. Just remember that Albinism is a recessive disease. They have given uh the frequency of aa and wants u to calculate Aa

Answer 14

You can workout ur question in same manner. Just remember that Albinism is a recessive disease. They have given u the number of aa so and wants u to calculate number of Aa. Frequency of aa will be 250/100000.

Answer 15

Hope it helps !
