Female gametes in a plant have genotypes TR, Tr, tR and tr with respect to height (T/t) and flower colour. (R/r). What will be the phenotype of this plant?

Options:

Answer:
B
Solution:

The gametes produced by the plant are TR, Tr, tR, and tr.

Since the gametes contain both dominant and recessive alleles for both traits (T and t for height, R and r for flower colour), the parent plant must possess all these alleles.

This indicates that the plant is heterozygous for both genes. Thus, the genotype of the plant is TtRr.

The phenotype corresponding to the genotype TtRr is heterozygous tall and heterozygous red.

Answer: Heterozygous tall; Heterozygous Red (TtRr).
