Genetics: Understanding Dominant Genes

It can produce the same phenotype regardless of allele identity. (correct)

It always results in a recessive phenotype.

It cannot be expressed in homozygous conditions.

It is always more common than recessive genes.

When both alleles are recessive.

If one allele is recessive and the other is dominant. (correct)

Only when both alleles are identical.

In the absence of any gene expression.

Dominant genes produce identical phenotypes in all individuals.

Dominant genes have no effect in presence of recessive alleles.

The presence of a dominant gene guarantees a dominant phenotype. (correct)

A dominant gene will not affect the phenotype if heterozygous.
