Question

Every time mendel performed dihybrid cross he found two parental combinations and two new. which principle did he apply ? and what law was established.

Answer 1

While performing the dihybrid cross, Mendel applied the principle of segregation and thought that both the alleles would segregate and thought that only two phenotypes would be seen in the progeny. However, he found four phenotypes in the ratio of 9:3:3:1, two of which were parental combinations and two recombinants. This established the law of independent assortment, according to two which when two homozygous parents differing in a pair of traits are crossed, the alleles of the two traits assort (distribute) independently of the parental combinations.
