How does probability relate to the punnett square and the offspring?
each outcome listed has a
a punnett square takes two people with certain genotypes, and lists all the possible genotypes of their offspring.
this diagram takes the genotypes of a heterozygous mother and father. both have genotype Aa.
since each genotype has two alleles, and there are two genotypes, the number of possible outcomes is
the probability of a certain combination of alleles in the offspring is the number of times it appears in the punnett square divided by the total number of combinations in the punnett square.
if you wanted to find the probability of an
total number of possible genotypes:
