A plant is heterozygous for height (Tt) and red flowers (Rr). What possible

gametes will this plant produce?

The possible gametes by a plant heterozygous for height (Tt) and red flowers (Rr) are TR, Tr, tR and tr.

Explanation:

According to the law of genetics, when heterozygous traits are crossed, the gametes would be one homozygous dominant gamete, two heterogygous gametes and one homozygous recessive. Hence, the possible gametes produced by a plant heterozygous for height (Tt) and red flowers (Rr) are TR, Tr, tR and tr. While, TR is the homozygous dominant gamete, Tr, tR are the heterogygous gametes and tr is the homozygous recessive gamete.

The correct answer for the question shown above is definitely the last option D. T or t because pea plant is able to carry any of the allele.
