Question
Chapter 34.4, Problem 1CC
Summary Introduction
To analyze:
The reason behind red-green color blind not common in females.
Introduction:
Red-green colorblindness is a disorder which is sex linked inheritance. The genes of the green and red color receptor are located on the X-chromosome. It is also termed as color vision deficiency in this disorder the person have a very low efficiency in differing between colors.
