In garden pea
(Pisum sativum), a plant with red flowers was
crossed with a plant with white flowers. Work out the possible genotypes and phenotypes of F1 and F2 generations. State any one of Mendel's law which
could be derived from this cross.

Expert Answer
Mendel's law of dominance can be deduced from the above cross. The hybrid is heterozygous containing both the alternative alleles (R and r). However, only one trait, i.e. red colour appeared and the white colour trait was suppressed in the F1 generation. So, we can conclude that the red colour trait is dominant over the white colour trait. This explains Mendel’s law of dominance.
