What is a dominant trait?

Back

A dominant trait is a genetic trait that always shows up in an organism when the allele is present.

Front

What does it mean if a trait is heterozygous?

Back

The alleles are different.

Front

Define recessive trait.

Back

A recessive trait is a genetic trait that only shows up when two recessive alleles are present.

Front

What is the difference between homozygous and heterozygous?

Back

Homozygous means having two identical alleles for a trait, while heterozygous means having two different alleles.

Front

What is an allele?

Back

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

Front

Explain incomplete dominance.

Back

Incomplete dominance is a genetic situation where one allele does not completely dominate another, resulting in a phenotype that is a blend of both.

Front

What is a genotype?

Back

A genotype is the genetic makeup of an organism, represented by the alleles it possesses.
