In the heterozygous state (w /w), a variegated eye is produced, with white and red patches. How might one explain position-effect variegation in terms of histone acetylation and/or deacetylation?Select all that apply.
a. The white patches are caused by the acetylation of the histones associated with the DNA of the w + allele.
b. The white patches are caused by the deacetylation of the histones associated with the DNA of the w + allele.
c. The red patches are caused by the acetylation of the histones associated with the DNA of the w + allele.
d. The red patches are caused by the deacetylation of the histones associated with the DNA of the w + allele.
