Question

Which heredity principle can be derived from a cross showing 3:1 ratio in the F₂ generation?

Answer 1

The Mendel’s law of segregation predicts the 3:1 dominant-to-recessive phenotypic ratio among the F2 generation of a monohybrid cross.

Alleles of two or more pair of genes categorize individually during the gamete formation;

so that the gametes with all likely amalgamation are formed in equal frequencies.

For eg Every egg or pollen grain transmits only one of each pair of parental alleles.
