What is a Punnett square?

Back

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

Front

What does each box in a Punnett square represent?

Back

Each box represents a possible offspring resulting from the combination of alleles from the parents.

Front

Define 'allele'.

Back

An allele is a variant form of a gene that can result in different traits.

Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles express their trait even if only one copy is present, while recessive alleles require two copies to express their trait.

Front

What is a phenotype?

Back

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

Front

What is a genotype?

Back

The genotype is the genetic makeup of an organism, representing the alleles it possesses.

Front

What does 'T' represent in genetics?

Back

In genetics, 'T' typically represents a dominant allele, such as for tall plants.

Front

What does 't' represent in genetics?

Back

In genetics, 't' typically represents a recessive allele, such as for short plants.

Front

What is a trait?

Back

A trait is a characteristic that is inherited and can be either dominant or recessive.

Front

What is the phenotype for a genotype of 'Tt'?

Back

The phenotype for 'Tt' is tall, as the dominant allele 'T' is expressed.
