What is the probability of an offspring showing a recessive trait if both parents are heterozygous?

Back

25%.

Front

What is an allele?

Back

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

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 a dominant trait?

Back

A dominant trait is a trait that will appear in the phenotype even if only one allele is present.
