Question

A group of ice age humans that numbered 100 migrated and joined a larger group of humans that numbered 400. With regards to a gene for the enzyme hormone-sensitive lipase which is involved in fat metabolism, the smaller group of 100 had allele frequencies of L = 0.75 and 1-0.25. The larger group had allele frequencies of L = 0.60 and 1-0.40, what is the new allele frequency of the L allele in the combined population after migration? Give your answer as a percentage value (i.e. if the decimal value is 0.40, enter 40

Answer 1

45%

Step-by-step explanation:

According to the Hardy-Weinberg Equilibrium equation, heterozygotes are represented by the 2pq

term. Therefore, the number of heterozygous ice age humans (Aa) is equal to 2pq which equals

2 × 0.6 × 0.75 = 0.45 or 45%
