Question

calculate the no of homozygous dominant plant if the no of homozygous recessive plant is 360 out of 1000​

Answer 1

the no. of homozygous dominant plant is 360

Explanation:

The ratio is 1:2:1

we know the no. of homozygous recessive plant is 360 so the no. of homozygous Dominant plant is also 360 and the heterozygous plants showing the dominant character will be 720

Answer 2

The frequency of the recessive allele.

Since we believe that the homozygous recessive for this gene (q2) represents 4% (i.e. = 0.04), the square root (q) is 0.2 (20%).

The frequency of the dominant allele.

Since q = 0.2, and p + q = 1, then p = 0.8 (80%).

The frequency of heterozygous individuals
