Question

If an offspring has genotype aabb, what possible combinations of parental genotypes can exit?

Answer 1

Answer:

Predicting the genotype of offspring There are four possible combinations of gametes for the AaBb parent. Half of the gametes get a dominant A and a dominant B allele; the other half of the gametes get a recessive a and a recessive b allele. Both parents produce 25% each of AB, Ab, aB, and ab.
