What is the purpose of studying the genotypes of parents?
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?
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?
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
