IMMEDIATE HELP NEEDED

Analyze the results of a cross between two organisms that are both heterozygous for two different genes (AaBb). Use a Punnett square to evaluate the possible genotypes. (1) List all the genotypes from your Punnett Square in the answer space. (2) Determine how many phenotypes can be produced in the offspring. (3) Determine the probability of producing offspring with the aabb genotype. (3 points)

So, did you watch that YouTube link I had in one of the posts?

anonymous · Answer

no wolf and i hve no time to watch a video :( im being timed.

anonymous · Answer

potential offspring genotypes are AABB, AABb, AAbb, AaBB, AaBb, Aabb, aaBB, aaBb, aabb.

anonymous · Answer

This is a standard dihybrid cross.

Phenotypes are 9:3:3:1
aabb = 1/16

i need more help though im still lost on the question
