Summer squash color is determined by the interaction of more than one gene.  The presence of CC or Cc allele combinations produces a squash that is white in color, and the C allele is epistatic to the G allele.  The presence of GG or Gg produces a squash that is yellow in color, and ccgg produces a squash that is green. After two fully heterozygous squash are crossed. Give the phenotypes, and frequency of occurrence, of the F2 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.
