In a genetic cross, if the phenotypic ratio of the offspring is 9:3:3:1, what type of cross was performed?

In a genetic cross, if the phenotypic ratio of the offspring is 9:3:3:1, what type of cross was performed?

Step 1: Understand what a phenotypic ratio is. It shows the different traits that appear in the offspring.
Step 2: Recognize that a 9:3:3:1 ratio is a specific pattern that occurs in genetics.
Step 3: Know that this ratio comes from a dihybrid cross, which involves two traits.
Step 4: Remember that a dihybrid cross typically involves parents that are both heterozygous for two traits.
Step 5: Conclude that if you see a 9:3:3:1 ratio in the offspring, it means a dihybrid cross was performed.
