Consider a gene with four alleles a1, a2, a3, and a4. if the cross a1a2 × a3a4 yields two offspring, what is the probability that both of them have the same genotype?

There are 4 possible genotypes among any offspring (2 possible alleles from either A1 or A3, and 2 possible alles from either A2 or A4; 2*2=4), all of which are equally likely to occur with probability 1/4.

The probability that 2 offspring have the same genotype is (1/4)^2 = 1/16.

the answer is c.

step-by-step explanation:

the correct answer would be the third option
