The flies with variegated eye color had what abnormal chromosome structure following x-ray exposure? group of answer choices
o x-chromosome translocation that moves the w+ gene to a region of heterochromatin on another chromosome in some cells.
o x-chromosome inversion that moves the w+ gene to a different orientation on the chromosome in some cells.
o a mutation in a somatic chromosome that causes the w+ gene to be translocated to the x-chromosomes.
o x-chromosome deletion that deleted the w+ gene in some cells.
o a mutation in the w+ gene that causes the gene to be overexpressed in a tissue-specific manner.

The inversion of X-chromosome resulting in the movement of w+ gene to certain cell chromosomes.

Explanation:

The mutation was first observed by Hermann Muller, in the year 1930.The eye colour variegation of flies is the result of unusual gene juxtaposition in certain cells through transposition. The translocation of gene in Drosophila the chromosome X gets inverted and places the w+ gene beside the heterochromatin.

Later, through the mutation the eye color becomes variegated and the gene is moved to certain cells of eyes, unlike the phenotype of red eye.
