	Adds acetyl groups to histones
HMT
HDAC
	Removes methyl groups from histones
DMT

A moth census on Wooded Island counted 100 black (BB) moths, 40 gray (Bb) and 60 white (bb) moths. What are the genotypic frequencies? What are the allelic frequencies? Is the population in Hardy-Weinberg equilibrium?

Expert Solution

Name of The enzyme	Function	Writer or eraser
HMT ( Histone aceytl transferase)	Add acetyl groups to histone	Writer ( Histone acetyl transferase enzymes modify histones by addition of acetyl group.)
HDAC ( Histone deacetyltransferase)	removes methyl group from histone	Eraser ( they might me associated with the repressor.)
DMT ( DNA methyltransferase)	add methyl group to DNA molecule	Eraser ( DNA methylation acts as a repressor)

2) Therefore the genotypic frequency of

BB = 0.5

bb = 0.0006

The allelic frequency of

B = 0.98

b =. 0.02
