Genetics of Hairless Guinea Pigs Amoeba Sisters w/video

What is the primary reason the teacher wanted a hairless guinea pig?

• For classroom experiments

• They are easier to care for

• Because they are rare

• For genetic studies

What does a lowercase 'h' represent in guinea pig genetics?

• A recessive allele for hairlessness

• A homozygous dominant condition

• A dominant allele for hair

• A heterozygous condition

What genotype represents a hairless guinea pig?

• Hh

• HH

• HHh

• hh

What does 'homozygous' mean?

• Having two identical recessive alleles

• Both B and C

• Having two different alleles

• Having two identical dominant alleles

A guinea pig with which genotype will have hair?

• hh

• Hh

• HH

• Both B and C

What is the purpose of a Punnett square?

• To confirm the phenotype of an organism

• To predict the possible genotypes of offspring

• To determine the actual genotype of an organism

• To predict the color of guinea pigs

In a monohybrid cross of two heterozygous guinea pigs, what is the expected ratio of offspring with hair?

• 4:0

• 2:1

• 3:1

• 1:1

What does the phenotype ratio 3:1 indicate in a Punnett square?

• 3 recessive to 1 dominant

• 3 dominant to 1 recessive

• 3 with hair to 1 hairless

• 3 hairless to 1 with hair

Why are Punnett squares considered predictions?

• They determine the exact phenotype of offspring

• They always provide accurate results

• They show probabilities, not certainties

• They can only be used for guinea pigs
