In rabbits, the gene that codes for a spotted coat is dominant over the gene that codes for a solid coat, and the gene for the coat's black color is dominant over the gene for the coat's brown color. If a spotted, black-coated rabbit mates with a solid, brown-coated rabbit, what are the genotypes and phenotypes of their offspring?

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.
