Question: If A/A x B/B is crossed with a/a and the F1 is testcrossed, what is the genotype and percenage of each progeny if the two genes are (1a) unlinked; (1b) completely linked (no crossing over at all); (1c) 16 m.u. apart? The genotypes in your answer must use "A" or "a" and "B" or "b" letters.
