Question

A homozygous plant having round (R) and yellow (Y) seed is crossed with homozygous plant having wrinkled (r) and green (y) seeds:
(a) Give the scientific name of the plant on which Mendel conducted his hybridisation experiments.
(b) Give the genotype of the F1 generation.
(c) Name and state the law which explains the dihybrid ratio.

Solution

(a) Pisum sativum (sweet pea).

(b) Genotype of F1 generation is heterozygous round yellow seeds (RrYy)

(c) Law of Independent Assortment: When there are two pairs of contrasting characters, the distribution of the alleles of one pair into the gametes is independent of the distribution of the other pair.
