Independent assortment means that:   the segregation of one gene pair occurs as if no other gene pairs were presen the gametes must be heterozygous in all cases the phenotypic ration of the F2 generation will be the same for both mono- and dihybrid crosses the segregation of one gene pair depends on the segregation of other gene pairs monohybird crosses will show segregation and independent assortment

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.
