A population of pea plants has 25% dwarf plants and 75% tall plants. the tall allele, t, is dominant to dwarf (t). what percenta
galina1969 [7]

Here we would be using Hardy Weinberg equation for the calculation of allele and genotypic frequencies.

Dwarf genotype frequency = q^{2} = 25% = 0.25

Frequency of allele t = q = \sqrt{q^{2}} = \sqrt{0.25} = 0.5

According to the equation,

p + q = 1

p = 1 - 0.5 = 0.5

Now, the frequency of heterozygous tall plants would be-

2pq = 2 * 0.5 * 0.5 = 0.5 or <u>50% heterozygous tall plants</u>.
