In a population of 100 individuals, the number of homozygous recessives is 4. Let’s assume that you can distinguish the heterozygotes from the homozygous dominants. There are 80 heterozygotes, and 16 homozygous dominants.b. What is the frequency of each allele?c. What would you estimate the allele & genotype frequencies to […]

There are two different species of single-cell organisms (each organism consists of only one cell) living in the same environment. The two are identical except that the members of one species are four times larger than the other species. Suddenly their environment becomes dramatically worse: the nutrients that each species […]
