In a Hardy-Weinberg population with two alleles, G and g, that are in equilibrium, 40% of the alleles are recessive. What percentage of the population is homozygous for the dominant allele? a. 9% b. 36% c. 70% d. 60% e. 30%

In horses, tobiano is a white spotting pattern. The tobiano allele (T) is dominant over the non-tobiano (t) allele. In an ideal horse population exhibiting Hardy–Weinberg equilibrium, 350 horses out of 465 are non-tobiano.    a. Calculate the number of homozygous dominant tobiano horses.   Answer b. Calculate the number of heterozygous horses.                               Answer c. Calculate the number of tobiano horses in the population.            Answer   Express your answer rounded to the nearest whole number.

There is a population of cats and 16% of the cats this population show a recessive trait. a. What is the frequency of the recessive allele? b.  What is the frequency of the dominant genotype?  c.  What is the frequency of cats with the heterozygous genotype?

You are surveying population genetics of snails while studying abroad in New Zealand.  At your locus of interest, you have AA: 32 Aa:46 aa: 22.  Identify the statement that accurately describes this population.   a. The genotype frequency of AA is 0.77.   b. The frequency of the A allele is  0.45.   c. The genotype frequency of the heterozygotes is 0.45.   d. The frequency of the a allele is 0.23.
