Question: In a test cross, an individual with a dominant phenotype is crossed with which type of individual?

Options:

Correct Answer: Homozygous recessive

Solution:

A test cross is performed by crossing an individual with a dominant phenotype with a homozygous recessive individual to determine the genotype.

In a test cross, an individual with a dominant phenotype is crossed with which type of individual?

In a test cross, an individual with a dominant phenotype is crossed with which type of individual?

Step 1: Understand what a dominant phenotype is. This means the individual shows a trait that is dominant, like having brown eyes.
Step 2: Know what a homozygous recessive individual is. This means the individual has two recessive alleles, like having blue eyes.
Step 3: Realize that a test cross is used to find out the genotype of the dominant phenotype individual.
Step 4: To perform a test cross, you cross the individual with the dominant phenotype with a homozygous recessive individual.
Step 5: Analyze the offspring to determine the genotype of the dominant phenotype individual based on their traits.

Test Cross – A genetic cross used to determine the genotype of an individual with a dominant phenotype by crossing it with a homozygous recessive individual.
