The flies with variegated eye color had what abnormal chromosome structure? A) X- chromosome deletion that deleted the w⁺ gene in some cells following X- ray exposure B) X- chromosome inversion that moves the w⁺ gene to a different orientation on the chromosome in some cells following X- ray exposure C) a mutation in the w⁺ gene following X- ray exposure that causes the gene to be overexpressed in a tissue- specific manner D) a mutation in a somatic chromosome that causes the w⁺ gene to be translocated to the X- chromosomes following X- ray exposure E) X- chromosome translocation that moves the w⁺ gene to a region of heterochromatin on another chromosome in some cells following X- ray exposure

Question

Quizplus · Accepted Answer

The correct answer involves an X-chromosome inversion that changes the orientation of the w⁺ gene on the chromosome, which can lead to variegated eye color in flies due to the gene being expressed differently in some cells.
