Punnett Square Help

1)
Set up a Di-hybrid cross for these two traits (pod color and shape)
Note:Green pods are dominate over yellow pods and inflated pods are dominant over constricted pods

-Start off with both parents as heterozygotes/hybrids for BOTH genes and assume the genes are located on different chromosomes

-Determine the genotypes and phenotypes of the offspring.

To set up a dihybrid cross, you need to consider two traits (in this case, pod color and shape) and their corresponding alleles. Let's go step by step to solve this problem:

Step 1: Understand the traits and their dominance. In this case, green pods are dominant over yellow pods, and inflated pods are dominant over constricted pods.

Step 2: Determine the parental genotypes. As stated, both parents are heterozygotes for both genes and the genes are located on different chromosomes. Let's represent the dominant alleles with capital letters (G for green, I for inflated) and the recessive alleles with lowercase letters (g for yellow, i for constricted).

Parent 1: GGii (Green color, Constricted shape)
Parent 2: ggII (Yellow color, Inflated shape)

Step 3: Write out the Punnett Square. Write the alleles for one parent along the top row (GGii) and the alleles for the other parent along the left column (ggII).

g g
G GGii GGii
G GGii GGii

I GiI GiI
I GiI GiI

Step 4: Combine the alleles in the square cells. The allele combinations will give you the potential genotypes and phenotypes of the offspring.

Let's consider the first cell (top left cell of the Punnett Square):
- The allele combination is GgIi.
- Gg represents the genotype for pod color. Since green is dominant over yellow, the phenotype will be green.
- Ii represents the genotype for pod shape. Since inflated is dominant over constricted, the phenotype will be inflated.

Repeat this process for all the cells in the Punnett Square to find the genotypes and phenotypes of all possible offspring.

Remember that there are two rows and two columns, so a total of four squares in the Punnett Square.
