Question

Part b - determining gamete genotypes in trihybrid crosses you have also identified a third recessive mutation that you call crimson. wasps homozygous for crimson have a red abdomen. (wild-type abdomens are yellow.) you make pure-breeding crimson (cc) and triple-mutant (apricot, blunt, crimson) lines. to map the three loci, you perform a trihybrid (three-point) testcross: you first cross crimson wasps with (apricot, blunt) wasps to make an f1, and then you testcross the f1 with the triple-mutant line.

Answer 1

The following are the answers - determining gamete genotypes in trihybrid crossesForeseeing the genotype of offspring. There are four possible combinations of gametes for the AaBb parent. 
A - B Column: non / non / REC / REC B - C Column: REC / non / non / REC A - C Column: REC / non / REC / non

Answer 2

Gamete Genotype

Determining the gamete genotypes in trihybrid crosses it is also identified a third recessive mutation that is commonly called as crimson. Foreseeing the genotype of offspring is as follows described. It can be four feasible blends of gametes for the AaBb parent are as:

A - B Column: non / non / REC / REC

B - C Column: REC / non / non / REC A -

C Column: REC / non / REC / non
