Figure 3 depicts two diploid cells containing two pairs of homologous chromosomes from a male and female of the same species. The larger chromosomes have different alleles of gene D, and the smaller chromosomes have different alleles of gene E.

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.
