Questions and Answers

What is the purpose of studying the genotypes of parents?

To determine the color of the offspring's fur

To identify the gender of the offspring

To study the environment in which the offspring will grow

To predict the probability of offspring having specific genotypes and phenotypes (correct)

In a dihybrid cross Punnett square, why does the number of boxes increase exponentially?

Because each trait possesses multiple alleles

As a result of having two different traits being considered (correct)

Due to the separate segregation of alleles for each trait

Because recessive traits are more common than dominant traits

What does having a 6.25% chance of offspring possessing both homozygous recessive traits indicate?

There is a low probability of both traits being expressed (correct)

Both parents must have dominant traits

The offspring will have a genetic disorder

The parents have the same genotype
