Question
In a hypothetic diploid population of chocolate eaters, a dominant allele A determine preference for dark colored chocolate and recessive allele a is for light colored chocolate. It was found that there are 2345 indivuals prefer light colored chocolate and 8765 ibdivuals perferdark. This population is in hardy weinburg equilbrim.
1) estimate the allele frequencies.
2) estimate how many indiuvals are heterozygous for chocolate preference with genotype Aa?
Moving to another question well save this response. In a hypothetic diploid population of chocolate eaters, a dominant allele A determine preference for dark colored chocolate and recessive allele a is for light colored chocolate. It was found that there are 2345 individuals prefer light colored chocolate and 8765 individuals prefer dark. This population is in Hardy Weinberg equilibrium with respect to chocolate preference. 1) Estimate the allele frequencies Procedures are required. 2) Estimate how many individuals are heterozygous for chocolate preference with genotype Aa? Procedures are required.Explanation / Answer
The total population be 11110. Out of which 2345 individuals prefer light chocolate and 8765 prefer dark chocolate.
Hardy Weinberg principle states-:
p+q=1
where p is the allele for homozygous dominant and q is the allele for homozygous dominant.
Also p2 + q2 +2pq =1
Where 2pq is the hetezygous population.
q2=2345/1110=0.21
q=0.45
The allele frequency for individuals prefer light colored chocolate is
q=0.45
The allele frequency for individuals prefer dark chocolate is
p= 1-0.45 =0.55
The hetezygous individuals for chocolate preference with genotype Aa is
2pq =2x0.45x0.55
=0.49
=0.49x1110
=543.9~544 individuals.
