Q. In a three-point testcross the nonrecombinant progeny are A+B+ C+ and a b c. The double crossover progeny are A+ B+ c and a b c+. Which gene is in the middle and why?
Answer.
Nonrecombinant progeny: A+ B+ C+ and a b c Double - crossover progeny: A+ B+ c and a b c+ By comparing both we found out that position the C gene is in the middle.

A wild-type trihybrid soybean plant is crossed to a pure-breeding soybean plant with the recessive phenotypes pale leaf (1), oval seed (r), and short height (t). The results of the 3-point test cross are show below. Traits not listed are WT. a)What are the alleles on each homologous chromosome of the parental wild-type trihybrid soybean plant? Place the alleles in their correct gene order. Use L, R, and Phenotype Number Pale 648 Pale, oval Pale, short Pale, oval, short 64 10 I to represent dominant alleles and I, r, and t for recessive 102 alleles.
