What does homozygous mean?

Back

Homozygous refers to having two identical alleles for a particular gene, such as BB or bb.

Front

In a Punnett square, what does each box represent?

Back

Each box in a Punnett square represents a possible genotype of the offspring resulting from the combination of parental alleles.
