In a pea plant that is heterozygous for seed color what

proportionof gametes will carry the recessive allel?

3/4

1/2

1/4

none above.

1/4.

Explanation:

The Mendel is known as father of genetics. He explained the concept of dominance, law of segregation and law of independent assortment while working on the pea plant.

The cross between the heterozygous seed color (Ss * Ss), result in the 3/4 dominant phenotype (SS, Ss and Ss) and 1/4 recessive phenotype with alleles ss.

Ss * Ss

progeny obtained are SS, Ss, Ss and ss.

Thus, the correct answer is option (3).
