Punnett Squares

Front

What do dominant alleles represent in genetics?

Back

Dominant alleles are represented by a capital letter.

Front

What is a homozygous dominant genotype?

Back

A homozygous dominant genotype consists of two identical dominant alleles, represented as 'AA'.

Front

What probability does each box in a Punnett Square represent for an offspring's genotype?

Back

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

Front

What does heterozygous mean in genetics?

Back

Heterozygous means the alleles are different, such as 'Aa'.

Front

What is an example of a homozygous recessive genotype?

Back

An example of a homozygous recessive genotype is 'tt'.

Front

What is a Punnett Square used for?

Back

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

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup (e.g., 'AA', 'Aa', 'aa'), while phenotype refers to the observable traits (e.g., flower color).

Front

What does it mean if an organism is homozygous?

Back

An organism is homozygous if it has two identical alleles for a trait, either dominant or recessive.

Front

What does it mean if an organism is heterozygous?

Back

An organism is heterozygous if it has two different alleles for a trait.

Front

How do you represent a recessive allele in genetics?

Back

A recessive allele is represented by a lowercase letter.
