This simple guide will walk you through the steps of solving a typical dihybrid cross common in genetics. The method can also work for any cross that involves two traits. Consider this cross A pea plant that is heterozygous for round, yellow seeds is self fertilized, what are the phenotypic ratios of the resulting offspring?

Step-by-step solution. Because there are two traits here, we must perform a dihybrid cross. We know the parent genotypes (Bbhh and bbHh), but we need to figure out what the possible gametes are by figuring out all the possible combinations of the two alleles.For the Bbhh parent, the possible gamete combinations are Bh, Bh, bh, or bh.. For the bbHh parent, the possible gamete combinations are.

Dihybrid Cross Worksheet In peas, round seed shape (R) is dominant to wrinkled seed shape (r), and yellow seed color (Y) is dominant to green seed color (y). A pea plant which is homozygous round seed and has green seed color is crossed with a pea plant that is heterozygous round seed shape and heterozygous yellow seed color. Example: RRyy X

A dihybrid cross worksheet will help to predict and determine the genotype of an offspring. It does this by determining all the possible combinations of alleles in the gametes of each of the parents. As an example, half of the gametes get a dominant S and a dominant Y allele. The other half get a recessive s and a recessive y allele.

Dihybrid Crosses Practice Problems. Two sets of genes on different chromosomes are responsible for the coat color in an animal X. Gene B codes for the brown color and gene G for grey. Beige-colored coat results when these genes are in heterozygous condition and in case both the genes are recessive, the coat color is white. Suppose, a male of X.
