A particular gene in dogs contributes to coat color. The two alleles exhibit incomplete dominance.  Dogs with genotype mm have normal pigmentation; genotype Mm leads to “dilute” pigmentation; genotype MM produces an all-white dog.  If a breeder mates a normal dog with a white dog, what will be the genotypes and phenotypes of the puppies?  If two Mm dogs are mated, what is the probability that a puppy will be white?

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.
