Punnett Squares

Front

What does each box in a Punnett Square represent?

Back

Each box represents a 25% probability of an offspring's genotype.

Front

What allele combination is represented by 'Aa'?

Back

Aa is a heterozygous genotype, meaning it has one dominant and one recessive allele.

Front

Which genotype is considered purebred?

Back

PP is a purebred genotype, as it has two identical dominant alleles.

Front

What is the definition of phenotype?

Back

Phenotype refers to an organism's physical appearance or visible traits.

Front

What is a dominant allele?

Back

A dominant allele is a trait that always shows up in an organism when the allele is present.

Front

What is a recessive allele?

Back

A recessive allele is a trait that only shows up when two copies are present.

Front

What is the purpose of a Punnett Square?

Back

A Punnett Square is used to predict the genotypes of offspring from parental genotypes.

Front

What does homozygous mean?

Back

Homozygous refers to having two identical alleles for a particular gene.

Front

What does heterozygous mean?

Back

Heterozygous refers to having two different alleles for a particular gene.

Front

What is the genotype of an organism?

Back
