In horses, assume that there are three colors affecting genes with the following effects: AA is lethal, Aa is white (albino), and aa allows color. B_ is black and bb is chestnut. D_ is solid and dd has white spots on color. (Albino would not show spots). A stallion that is heterozygous for all three genes and a mare of genotype AaBbdd are mated. a. What color is the mare and what are the genotypes of the gametes she produces? b. What is the color of the stallion and what are the genotypes of the gametes he produces? c. Construct a Punnett square and determine the frequencies of phenotypes that would be expected in the LIVE offspring.

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
