A male with red green colorblindness mats with a female carrier.

If a female xbxb is a carrier for red green colorblindness marries a male xby who is not colorblind and they have children what is the likelihood that they would produce a colorblind daughter. If a female x bx b is a carrier for red green colorblindness marries a male x by who is not colorblind and they have children what is the likelihood that they would produce a colorblind daughter. If the man is colorblind and the woman is not and she is not a carrier for colorblindness then their fema. Human beings have 23 different pairs of chromosomes whereof one pair is the so called sex chromosome.

A male who has color blindness xby mates with a carrier female xbxb. When an x chromosome contains the recessive allele the allele is written as xn. But my mother is xx. Color blindness is sex linked trait and its inheritance follows criss cross pattern.

So she isn t colorblind. 2 what is the genotype of a female who is not color blind but is a carrier of red green color blindness. This pair consists of two x chromosomes on women and one x coupled with one y chromosome on men. What is the probability that this couple will have a male child who is.

Even though red green color blindness is a recessive trait can a female have red green. Male and ddbb female interbreed. That s why colorblindness is much more common in men than in women.

This is why red green colour blindness is far more common in men than women. Blue yellow colour blindness affects both men and women equally because it is carried on a non sex chromosome.

But she is a carrier.
