Genetics and Traits of Guinea Pigs

What type of guinea pig did the teacher desire for the classroom?

• Hairless guinea pig

• Long-haired guinea pig

• Spotted guinea pig

• Albino guinea pig

What symbol is used to represent a recessive allele for hairlessness in guinea pigs?

• H

• h

• G

• B

If a guinea pig has one 'H' allele and one 'h' allele, what is its hair status?

• Hairless

• Hairy

• Spotted

• Bald patches

What does 'homozygous' mean in the context of guinea pig genetics?

• Recessive trait

• Same alleles

• Dominant trait

• Different alleles

What is the genotype of a hairless guinea pig?

• HhH

• hh

• Hh

• HH

In a Punnett square, what does the combination 'Hh' represent?

• Heterozygous

• Homozygous recessive

• Homozygous dominant

• None of the above

What percentage of offspring from two heterozygous guinea pigs are expected to be hairless?

• 25%

• 50%

• 75%

• 100%

What does the phenotype describe in genetics?

• Genetic makeup

• Physical traits

• Probability predictions

• Allele combinations

What is the phenotype ratio for hairy to hairless in the offspring of the discussed Punnett square?

• 3:1

• 1:3

• 2:2

• 4:0

Why are Punnett squares considered predictive in nature?

• They show exact outcomes

• They are based on past data

• They represent probabilities

• They are always accurate
