A human population containing 200 individuals has two alleles at the T locus, named T and t. T, which produces tall individuals, is dominant over t, which produces short individuals. If the population has 90 TT, 40 Tt and 70tt genotypes, what will be the frequencies of these two alleles in this population?A. T, 0.50 ; t, 0.50B. T, 0.55 ; t, 0.45C. T, 0.45; t, 0.35D. T, 0.90 ; t, 0.10

Hint: Inheritance is that the strategy by which hereditary data is given from parent to kid. This is frequently regularly why individuals from the indistinguishable family will in general have comparable qualities.

A populace with 200 individual has 90 TT, 40 Tt and 70 tt genotypes
For example, the prevailing allele (T) is TT + Tt. e. 90 + 90 + 40 $\Rightarrow$
220 Passive allele (t) is Tt + tt for example 40 + 70 + 70 $\Rightarrow$ 180
Dominant allele = 400 Dominant allele (T) recurrence = 220/400 = 0.55
Recessive allele (t) recurrence = $\dfrac{180}{400}$ = 0.45
Thus, from above clarification it'll be closed the right alternative is B
So, the correct answer is “Option b”.

$p^{2}$ + 2pq + $q^{2}$ = 1 and p + q = 1
$p^{2}$ = level of homozygous predominant people
$q^{2}$ = level of homozygous latent people
