What is the genetic material that codes for traits in guinea pigs?

• Proteins

• Lipids

• RNA

• DNA

What does a recessive allele require to be expressed in guinea pigs?

• One recessive allele

• At least one dominant allele

• Two dominant alleles

• No dominant alleles present

If hairless is recessive, what genotype represents a hairless guinea pig?

If a guinea pig has hair, and hair is a dominant trait, which of the following genotypes could it possibly have?

• Both HH and Hh

• hh

• Hh

• HH

What is the purpose of a Punnett square in genetics?

• To confirm the actual outcomes of a genetic cross

• To visualize DNA structure

• To predict the possible outcomes of a genetic cross

• To determine the exact sequence of genes

What does a phenotype ratio of 3:1 in guinea pigs indicate in a genetic cross?

• 3 hairless and 1 with hair

• 3 with hair and 1 hairless

• All with hair

• All hairless

Why are genetic outcomes considered probabilistic?

• They vary depending on environmental factors

• They are always certain and predictable

• They are predictions based on probability, not certainties

• They can be visually observed without experiments

What is the expected genotype ratio for a monohybrid cross between two heterozygous parents (Aa x Aa)?

• 1:2:1 (AA:Aa:aa)

• 3:1 (AA:aa)

• 2:1:1 (AA:Aa:aa)

• 1:3 (Aa:aa)
