The dominant white allele (W) is a homozygous lethal and is dominant over the full color allele (w) in horses. The “overo” paint-spotting allele (O) is also lethal when homozygous and it is dominant over the nonspotting allele (o). The dominant at the white locus, however, masks the paint phenotype. Two horses of the genotype WwOo are crossed. At what frequency is a full color (not painted and not white) horse expected from this cross?

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.
