Front

What are dominant genes?

Back

Dominant genes are stronger genes that can mask the effects of recessive genes.

Front

What are recessive genes?

Front

What does it mean for a trait to be inherited?

Back

An inherited trait is one that is passed down from parents to their offspring.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism, while phenotype refers to the observable traits.

Front

What is a homozygous genotype?

Back

A homozygous genotype has two identical alleles for a trait, either dominant or recessive.

Front

What is a heterozygous genotype?

Back

A heterozygous genotype has two different alleles for a trait, one dominant and one recessive.
