how many different allele combinations would be found in the gametes produced by a pea plant whose genotype was RrYY? A) 16 B) 8 C) 4 D) 2

Th genotype of the pea plant is RrYY, which shows that it has two genes that are corresponding to two different traits that are color ( Rr) and shape ( YY) of the seed.

During gamete formation, the alleles ( different forms of gene like R and r here) of these genes are segregated and enter in the gametes. There are two allele for the gene corresponding to color that is R and r, whereas gene for shape has only one type of allele that is Y.

Two different type of allelic combinations are found ( refer attachment) in the gametes, which are RY and rY.

The genotype of a pea plant is RrYY, which means it has two copies of each gene that correlate to two distinct features of the seed, color (Rr) and shape (YY).

During gamete creation, the alleles of various versions of genes, such as R and r in this case, are segregated and enter the gametes.
The color gene contains two alleles, R and r, but the shape gene has only one type of allele, Y.
Inside the gametes, two kinds of major allelic combinations are discovered, which are "RY" and "rY".

Therefore, the answer is "Option D".
