Question & Answer Hub
What is a Punnett square?
A Punnett square is a graphical representation that predicts the possible genotypes and phenotypes of offspring based on the genotypes of their parents.
How do I use a Punnett square?
Arrange the alleles of each parent along the sides of the square and fill in the boxes with the possible combinations of alleles for the offspring.
What is the difference between a homozygous and heterozygous genotype?
A homozygous genotype has two identical alleles for a particular gene, while a heterozygous genotype has two different alleles for the same gene.
