When Two Genes Are Linked, Most of the Phenotypes of the Parental

Multiple Choice

When two genes are linked, most of the phenotypes of the parental traits will be inherited together. For example, eye colour and bristle form in the vinegar fly, Drosophila, are linked. The alleles for white eyes and crooked bristles occur on one chromosome in a fly while the alleles for red eyes and straight bristles occur together on another chromosome. Gametes produced by the fly that contain a chromosome with both the white-eye allele and the straight-bristle allele are referred to as

A) incomplete dominants.
B) recombinants.
C) polymorphic.
D) heterozygotes.
E) mutants.
