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?

If the frequency of the dominant allele is 0.4, what is the frequency of the recessive allele?

If a male is homozygous dominant for a trait, that parent’s genotype might be DD. If the female is heterozygous for the same trait, her type would be Dd. a. How many genetically different sperm can the male produce? b. Using punnet square, determine the expected genotypic ratios of their offspring. c. What are the expected phenotypic ratios?

The ratio for offspring in a specific population is .35 Homozygous AA, .20 Heterozygous Aa, .45 Homozygous for aa. If the A gene is dominant orange and the gene is recessive blue what is the phenotype ratio that will be observed from this population?

Why are monozygotic twins genetically identical, whereas dizygotic twins share only 50% of their genes on average?a. Monozygotic twins tend to look more similar.b. Monozygotic twins develop from two different eggs fertilized by the same sperm, whereas dizygotic twins develop from two eggs fertilized by two different sperm.c. Monozygotic twins develop from a single egg fertilized by one sperm, whereas dizygotic twins develop from a single egg fertilized by two different sperm.d. Monozygotic twins develop from a single egg fertilized by a single sperm, whereas dizygotic twins develop from two eggs fertilized by two different sperm.

If 60 individuals have the genotype AA, 28 individuals have the genotype Aa, and 12 individuals have the genotype aaWhat is the frequency of the a allele?

We observe disruptive selection when the extreme values of a trait such as light and dark coat colors are selected for instead of a medium coat color? A. true  b. False
