27. A chromosome contains alleles forblue eyes and blond hair. After meiosis the same chromosomecontains alleles for blue eyes and brown hair. The chromosome isNOW said to be A. homologous. B. recombinant. C. aneuploid D. polymorphic E. autosomal 28. During a dihybrid cross involvingtwo linked genes, 18 percent of the resulting gametes showed arecombinant genotype. These two linked genes are .......... mapunits apart. A. 0.18 B. 180 C.1.8 D. 18 E.32 29. For a two-point testcross, if thepercentage of recombinants is 50 percent, the two genes maybe A. non linked. B. distant from each other on the same chromosome. C. on different chromosomes D. both A and B. E. all of the above. 27. A chromosome contains alleles forblue eyes and blond hair.
