Explanation / Answer
When a population is in Hardy Weinberg equilibrium then, p+q=1, where p and q are the gene frequency of two allele.
If P is the frequency of wild type gene and q is the Mutant gene then,
q2=22/220=0.1, then q=0.316
Then p=1-q=0.684, then 2pq=0.432.
Thus the heterozygous Frequency is 0.432 or 43.2%.
2. Thus the number of heterozygous bare in the population is approx. 95.
3.The mutant Cyc/cys genotype frequency is q2=0.1or 10%.
4.The Tyr / Tyr genotype frequency is p2= 0.468 or 46.8%.
5.Frequency of the Cys allele is q=0.316
