Question

according to geneticists today, what determines the size of a punnett square?
number of gametes
number of chromosomes
number of genotypes
number of alleles

Explanation:

A Punnett square is a diagram used to predict the genotypes of a particular cross or breeding experiment. The size of the Punnett square is determined by the number of different gametes each parent can produce. For example, if each parent can produce 2 different gametes, the Punnett square will be 2x2. If each parent can produce 3 different gametes, the Punnett square will be 3x3, and so on.

Answer:

number of gametes
