Simple Punnett Squares #2

Front

What is a Punnett Square?

Back

A Punnett Square is a diagram used to predict the genetic makeup of offspring from two parents based on their genotypes.

Front

What does Bb represent in genetics?

Back

Bb represents a heterozygous genotype, where one allele is dominant (B) and the other is recessive (b).

Front

What does bb represent in genetics?

Back

bb represents a homozygous recessive genotype, where both alleles are recessive.

Front

What is the phenotype of a person with genotype Bb?

Back

The phenotype of a person with genotype Bb is the dominant trait, which in this case would be brown eyes.

Front

What is the phenotype of a person with genotype bb?

Back

The phenotype of a person with genotype bb is the recessive trait, which in this case would be green eyes.

Front

What does phenotype mean?

Back

Phenotype refers to the observable physical traits of an organism, such as eye color or hair type.

Front

What does genotype mean?

Back

Genotype refers to the genetic makeup of an organism, represented by the alleles it possesses.

Front

What is a homozygous genotype?

Back

A homozygous genotype has two identical alleles for a trait, such as BB or bb.

Front

What is a heterozygous genotype?

Back

A heterozygous genotype has two different alleles for a trait, such as Bb.

Front

If a curly-haired mother (hh) and a curly-haired father (hh) have offspring, what is the probability of straight hair?

Back

0% of the offspring will have straight hair.
