In a mixed-sex population in Hardy-Weinberg Equilibrium, the frequency of colorblind females is 1%. Color-blindness is an X-linked recessive trait. Colorblind males in this population consist of:

This question and the previous one are based on the same information.In guinea pigs, black fur is an autosomal dominant trait, and white is the alternative recessive trait. A Hardy-Weinberg population of 400 guinea pigs was found to contain 64 white individuals.Consider ONLY the BLACK animals in this population. What PERCENTAGE of these animals is expected to be HETEROZYGOUS?

In this pedigree, a circle = female, and a square = male. Assume all individuals are homoplasmic, but people from different families have different DNAs. How many different mitochondrial DNAs are present in this pedigree?

A gene locus has four alleles with frequencies of A1 (0.1), A2 (0.2), A3 (0.3) and A4 (0.4). What is the frequency of the A2A3 genotype in a population that is in Hardy-Weinberg equilibrium?

Questions 28-30 are based on the same pedigree. This pedigree traces the inheritance of a rare autosomal recessive disease. Individual I-2 is known to be homozygous. Assume that q = 1/50 for this mutant allele, and that the population is in Hardy-Weinberg equilibrium. The chance of II-5 being a carrier is approximately

In a small population of cockroaches living in your kitchen, only a few roaches mate in one year. This can lead to random changes in allele frequency in the population through
