A Pea Plant is heterogeneous for height (Tt)

witch allele will be carried by a pollen grain produced by the plant?

A. T and t

B. t only

C. T or t

D. T only

The correct option is C) T or t

Explanation:

A heterogenous plant can be described as a heterozygous plant in which the alleles of a gene are different. For example, in the above question, the pea plant has one allele which is T and the other one which is t.

According to Mendel's law of segregation, the alleles assort independently at the time of gamete formation. Hence, there are equal chances that a gamete will carry T or t gene. Hence, the pollen grain will carry any one of the two alleles for the height gene.
