lation of wild norses consists o Black coat color in horses s conferred by the presence of a dominant B a ele chestnut horses are gen t pe b and 40 chestnut horses. Assume that this population is at Hardy-Weinberg equilibrium for this locus. Please round all answers correctly to 4 decimal digits. What is the frequency of the B allele? Apop n . iack orses Answer: Please round all answers correctly to 4 decimal digits. What is the frequency of the b allele? Answer Please round all answers correctly to 4 decimal digits. How many horses in the population are expected to be heterozygous for this locus? Answer:

Explanation / Answer

Total horses are 154+40= 194.

40/194= 0.2061 is q2.

So, q = 0.4539.

According to Hardy Weinberg equilibrium

p+q = 1.

So, p = 1 - 0.4539 = 0.5461.

So, frequency of B allele is 0.5461.

Frequency of b allele is 0.4539.

Frequency of heterozygotes are 2pq. That is 2*0.5461*0.4539 = 0.4597 that is 45.97% of population.

That is 96 horses will be heterozygous from the population.
