Front

What is a Punnett Square?

Back

A Punnett Square is a diagram used to predict the outcome of a genetic cross by showing the possible combinations of alleles from the parents.

What does 'T' represent in genetics?

Back

In genetics, 'T' typically represents a dominant allele for a trait, such as tallness in plants.

Front

What does 't' represent in genetics?

Back

In genetics, 't' typically represents a recessive allele for a trait, such as shortness in plants.

Front

What is the genotype for a homozygous tall plant?

Back

The genotype for a homozygous tall plant is TT.

Front

What is the genotype for a homozygous short plant?

Back

The genotype for a homozygous short plant is tt.

Front

What is the genotype for a heterozygous tall plant?

Back

The genotype for a heterozygous tall plant is Tt.

Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles are expressed in the phenotype even if only one copy is present, while recessive alleles are only expressed if two copies are present.

Front

What does it mean if an organism is homozygous?

Back

An organism is homozygous when it has two identical alleles for a particular gene.

Front

What does it mean if an organism is heterozygous?

Back

An organism is heterozygous when it has two different alleles for a particular gene.

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by its genotype.
