we will use the following
designations:
XBY--- male with normal vision XBXB---- female with normal vision
XbY---- male with colorblindness XBXb female carrier for
colorblindness XbXb ---female with colorblindness.
1. would there ever be an instance when a female could not be a
carrier? explain.
2. describe a test cross and explain why it is used.
Homework Answers
1. would there ever be an instance when a female could not be a carrier? explain.
No, as the females are diploid for X chromosome, if normal and defected x chromsomes are there, the phenotype will be the normal one. so, there is always a chance to be carrier.
2. Testcross: The cross between an individual and complete recesseive phonetype individual is called as test cross. The main purpose of the test cross is to study the genetical constitutaion of tested organism and to study the distance between the linked genes.

D. 25% orme condition. The male is XX and the female is XY. But X-linked genes have the same effects in mugwumps as in humans. A recessive X-linked allele "n" produces red-green color blindness. The dominant allele "N" produces normal color vision. If a female mugwump with normal color vision mates with a male mugwump, phenotypically normal for color vision but whose mother was color blind, what is the probability that a son from that mating will be color blind?...
