Given the nature of a punnet square, we can conclude that the ratio in question refers to the combination of genotypes present in the square.
A punnet square is a diagram used to attempt to predict the <u>genetic composition </u>for the <u>offspring</u> of certain parents, that is the genotype for this specific cross. This is done by creating a square in the form of a grid and placing the genotypes of the parents on the outside of this then crossing them along the inside.
This diagram provides us with the probability of each genotype outcome. This is known as the phenotype ratio. The phenotypic ratio is the amount of times a specific outcome, such as a certain pair of alleles appears in the predicted genotypes of any of the <u>offspring pertaining </u>to this <u>cross</u>.
