What does homozygous mean?

Back

Having two identical alleles for a particular gene.

What does heterozygous mean?

Back

Having two different alleles for a particular gene.

What is co-dominance in genetics?

Back

A situation where both alleles in a heterozygote are fully expressed.

Front

What is the difference between genotype and phenotype?

Back

Genotype is the genetic makeup, while phenotype is the physical expression of that makeup.
