Color blindness is a recessive sex-linked trait.?
Q. If a man with normal color vision and a woman who is a carrier for the color blindness trait have a son, what is the probability that he will be color blind? A. 0% B. 25% C. 50% D. 100%
Asked by speargirl - Thu May 15 15:32:34 2008 - - 2 Answers - 0 Comments
A. 50% The mother has genotype Xa Xb (where Xa means normal colour vision; Xb means colour blind) The son will get one X from his mother, either the Xa or Xb. So it's a 50-50 chance.

Why is color blindness referred to as a sex-linked trait?
Q. Under what conditions will a male be colorblind? How does this differ for a female?
Asked by spurschick - Sat Dec 12 21:09:09 2009 - - 1 Answers - 0 Comments
A. it is referred to as a sex-linked genetic disorder because it is in a sex chromosome (the X chromosome). In order for a man to be colorblind, his mom has to be a CARRIER of colorblindness. in order for a woman to be colorblind, the father must be colorblind. check out this site, under the section "linkage overview" hope this helps! =)

Can someone please help me understand my biology homework about color-blindness traits?
Q. I don't want to just be given the answers I need someone to explain to me how to get the answers so I understand (and I don't understand any of it). Thanks! Recall that females have two X chromosomes: one from the mother and one from the father. Males have one X chromosome and one Y chromosome; the X chromosome comes from the mother, and the Y chromosome comes from the father. Traits associated with genes located on the sex chromosomes are called sex-linked traits. The dominant allele for normal color vision is N. Individuals with the sex-linked condition called red-green color blindness do not perceive the colors red and green. Red-green color blindness is caused by the recessive allele n and is carried on the X chromosome. When an X… [cont.]

A. Sex linked traits can be a little confusing because you now have more than 2 possible alleles. You have both the chromosome for gender and the allele for the colorblind trait so you have XN (normal), Xn (colorblind), and Y. The Y chromosome doesn't have an area for a gene for color vision, so the colorblind trait can only be inherited from the X chromosome. So consider what the phenotypes (how the gene is expressed) for the possible combinations: XN XN (female, normal color vision) XN Xn (female with normal color vision, but carries the allele for colorblindness) Xn Xn (female, colorblind) XN Y (male, normal vision) Xn Y (male, colorblind) There's no way to have a male "carrier", he would either be colorblind or have normal vision… [cont.]

Asked by XsmilesX - Fri Mar 27 12:49:32 2009 - - 3 Answers - 0 Comments
A. The allele for colour blindness is recessive and sex linked (on the X chromosome), as men only have one X chromosome they will be colour blind if they inherit one copy (which will always come from the mother as this is where they inherit their X from as they get a Y from their father). However, women need two recessive alleles to be colour blind, if they have one they will be a carrier but will not actually be colour blind. So, for a woman to be colour blind, her father must be colour blind and her mother must be either colour blind or a carrier. Try watching this:

A. It's because since girls have 2 X chromosomes and males only have one X then all the genes are going to try to fit in that one X chromosome the male has and that's where colorblindness comes in, the gene for colorblindness is more likely to appear in males' genes because they only have 1 X chromosomes. well that's all I know hope I helped!
