Write a Hypothesis and Prediction of Table 1 182 25 dominant

Write a Hypothesis and Prediction of Table 1 (18.2)

25 dominant + 25 recessive + 50 heterozygous Allele Frequency Allele Frequency in the presence 100% negative selection pressure. Allele Frequency in the presence of 20% negative selection pressure. I already took 20% from bb

Solution

BB=29

Bb=52

Bb=20

BB=29/101=0.29

Bb=52/101=0.515

Frequency of B= 0.29+1/2(0.515) = 0.547

Frequency of b=1-0.547=0.453

.p²+ 2pq + q²= (0.29)² + (2*0.29*0.453) + (0.453)²=0.299+0.496+0.205=1

The population is in Hardy Weinberg equilibrium

Negative selection or purifying selection will take place in natural selection to remove the alleles which are deleterious, so that the population can go towards the stabilizing selection. But here in this case we did not see any negative selection as the frequency of both alleles B and b are more or less same.

So, we can hypothesize that the population is in Hardy Weinberg equilibrium
