Q: What is the expected genotypic ratio of a dihybrid cross?
Solution:
The expected genotypic ratio of a dihybrid cross is 9:3:3:1, representing the combinations of two traits.
Steps: 7
Show Steps
Step 1: Understand what a dihybrid cross is. It involves two traits, each with two alleles.
Step 2: Identify the alleles for each trait. For example, let's say Trait 1 has alleles A and a, and Trait 2 has alleles B and b.
Step 3: Create a Punnett square for the dihybrid cross. This will be a 4x4 grid because there are four combinations of alleles from each parent.
Step 4: Fill in the Punnett square with all possible combinations of the alleles from both traits.
Step 5: Count the different genotypes that appear in the Punnett square.
Step 6: Determine the ratio of each genotype. You will find 9 combinations of one type, 3 of another, 3 of a third type, and 1 of the last type.
Step 7: Write the expected genotypic ratio as 9:3:3:1.
