Carrier Green
How I can build this genealogy?
Build a family tree to answer the next question. color blindness is red-green a recessive trait linked to chromosome-X. A woman who has a color-blind mother and a father with normal vision marries a man with normal vision carrier. This couple has a son. What is the probability that the child is colorblind?
Well … restriction of a drawing, I can tell you is what, then maybe you can paste in a tree. It should be simple enough, the grandparents are on the top, below the parent in the child bottom – just google "letter pedigree "for examples. So N = normal vision and color blindness n. = nn woman = mother, the father of the woman = N (only one X chromosome). So the woman = Nn. She is a carrier, but has normal vision. husband of the woman = n. That is irrelevant as the child is concerned (because it inherits the Y), but you need to know your genotype for the pedigree. The child – a child – inherit their X chromosome from his mother and his Y chromosome from their father. What is inherited X chromosome is random – one who could inherit the gene N which would result in a normal view, or could inherit a gene with n and the inheritance of color blindness. So it is a probability 50% who is colorblind. Note that I ignored an inconsistency in the question to find the result, which states that the parent is a carrier, but has normal vision. The parent has only one X chromosome, so that is affected by color blindness or not – can not be a carrier. (I think there are some homologous regions between chromosomes X and Y, by so I guess that could fall within the assumption that, but the gene for color blindness is not there, so do not make sense.)
