In watermelons, the allele for green fruit is autosomal dominant (G) over the striped fruit (gg). The allele for short fruit (B) is dominant over the allele for ong fruit (bb). A green short watermelon plant that is heterozygous forr both traits is crossed with a striped long waterelon plant. What are the chances for their of their offspring to be striped and short?

Green short genotype:                                      Green short gametes allele:

Striped long genotype:                                    Striped long gametes allele:

Expert Answer

Step 1

The first set of parents crossed is called the “parental generation” or P-generation. All the offspring from the parents are the F1 or first filial generation. All the offspring obtained when the F1 individuals are interbred are the F2 or the second filial generation.

Step 2

This problem requires an understanding of independent assortment in a dihybrid cross and the ratios expected from monohybrid crosses.

Designate the alleles: G = green, g = striped, B = short, and b = long

Genotypes of the parents are,

Parent 1: green short watermelon plant is heterozygous for both traits = GgBb

Parent 2: striped long watermelon plant = ggbb

Step 3

The possible gametes for parent 1 are GB, Gb, gB, and gb

Parent 2 produce only one type of gamete, that is gb.
