NEET BIOLOGY

Detailed explanation-1: -Mendel crossbred round seed plants with wrinkled seed plants, it was observed that in F1 progeny, only round seed plants were obtained and no wrinkled seed plant was obtained. But in the F2 generation, both round and wrinkled seed plants were obtained in a 3:1 ratio.

Detailed explanation-2: -As a result of crossing these two pea variants, Mendel discovered that the round-seeded and wrinkled-seeded traits were two facets of the same character, suggesting to modern plant scientists that a single gene determines whether seeds are round or wrinkled.

Detailed explanation-3: -Understanding Dominant Traits For example, when Mendel cross-fertilized plants with wrinkled seeds to those with smooth seeds, he did not get progeny with semi-wrinkly seeds. Instead, the progeny from this cross had only smooth seeds.

Detailed explanation-4: -Dominant-Traits that appear to mask (or hide) other traits. Recessive-Traits that can be hidden in one generation and then appear in the next. Incomplete dominance-Traits in which the heterozygote shows a different phenotype from the homozygous dominant phenotype.
