In watermelons, solid green color (G) is dominant over striped pattern (g), and short shape (S) is dominant over long shape (s). What is the probability of each phenotype of possible offspring if a heterozygous solid, long watermelon cross pollinates with a heterozygous solid, heterozygous short watermelon?

Explanation:

The genotype for heterozygous solid and long is Gg ss and that for heterozygous solid and heterozygous short is Gg Ss.

The possible gamete combination for Gg ss are Gs and gs. And that for Gg Ss are GS, Gs, gS and gs.

Probability for:

Sold and short is 6/16 = 3/8

Solid and long is 6/16 = 3/8

Striped and short is 2/16 = 1/8

Striped and long is 2/16 = 1/8
