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).

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.
