What does it mean if an organism is heterozygous?

Back

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

Front

In genetics, what does the term 'allele' refer to?

Back

An allele is a variant form of a gene that determines a specific trait.

What is the dominant allele in the plant color example (P for purple, p for white)?

Back

P (purple) is the dominant allele.
