Red-green colorblindness is another genetic disorder, but is carried recessively on the X-chromosome. A red-green colorblind man who is a carrier for ataxia telangiestasia (AT) is married to a normal-vision woman who is not affected by AT, and does not carry the allele for the disorder. They have two children, a boy who is normal-vision and a girl who is red-green colorblind. Fortunately, neither child was diagnosed with AT. What is the probability that their next child will be a red-green colorblind girl who is a carrier of the allele for AT?

How likely is it that a Red-Green-Colorblind girl will be a carrier for AT? Exploring the genetics of Xlinked Disorders

The X-chromosome is a recessive genetic pattern that carries one of the most prevalent inheritance disorders: red-green colourblindness. This scenario involves a man, who is red-green and has telangiectasia carrier (AT), who marries a woman of normal vision who does not have AT. The two children they have, a boy (and a girl) are normal-vision, and both colorblind. Ataxia was not diagnosed in either child. Based on the above information, 25% of the chance that a girl with red-green vision is AT carrier is possible. The man has 50% of AT carriers in his family, so each child inherits the chance that they will be affected (Miyamoto, et al. 2016). Because her father is a carrier of AT, his daughter has a 50% chance that she will inherit the colorblindness gene. (Klein et. al. 2020). Combining these probabilities results in a 25% chance of having a daughter with AT who is red-green. Cont…
