Solution

Dihybrid cross:

  1. A cross between two parents that has two phenotypic features that are determined by two distinct genes is referred to as a dihybrid-cross.
  2. Scientist Gregor Mendel used the Pisum sativum plant in this experiment.
  3. The homozygous dominant Round and yellow seeds (AABB) and the homozygous recessive wrinkled and green seeds were crossed by him (aabb).
  4. The initial filial generation produced all-round and yellow seedlings (AaBb).
  5. These children carry both A and B genes and are heterozygous.
  6. Gametes from this generation include AB, Ab, Ba, and ab.
  7. The law of independent assortment is shown by this cross.
  8. As a result, the phenotypic ratio is 9:3:3:1, where yellow and round seeds are followed by round and green seeds, and then yellow and wrinkled seeds are followed by green and wrinkled seeds.
