Question

in a population of 400 induces frequency of recessive allele is 40 % find out which of these represent the total number of individuals with the dominant phenotype​

Answer 1

Explanation:

In the population of 400 individuals if 40% is recessive allele and 60% will be dominant (144).

So, the correct option is '144'.

Answer 2

Answer:

336

Explanation:

Please find the solution

Given recessive is 40% means 0.4 (q)

P+q = 1

Where P is dominant , q is recessive

P = 1 - 0.4

P = 0.6

According to formula

( p+ q) whole square

P square + 2pq+ q square = 1

P×p + 2pq+ q×q =1

0.6×0.6 + 2 × 0.6 × 0.4 + 0.4× 0.4 = 1

0.36 + 0.48 + 0.24 = 1

Thus

AA= 0.36 × 400 = 144

Aa = 0.48× 400 = 192

aa = 0.16× 400 = 64

As they are saying population with dominant phenotype thus add both AA + Aa

144+ 192 = 336 answer
