If red-green colorblindness is a sex-linked recessive trait and is prevalent in 1 out of every 12 males, what is its prevalence among women? One out of every 144? or....?
Red-green colorblindess is a sex-linked recessive trait. (Probability help!!!)?
I think your right.
Colourblindness affects 1 in 144 women, as I was told.
I also skips a generation. My dad's colourblind, which means my kids will be (if they're boys).
Reply:The incidence of recessive X-linked phenotypes in females is the square of that in males (squaring a proportion less than one gives an outcome closer to 0 than the original). If 1 in 20 males in a human population are green color blind, then 1 in 400 females in the population are expected to be color blind (1/20*1/20).
yes you are right, 1/144
Reply:I dunno, but I hate being colour-blind. Grass is very boring. Apparently, it's 1/12 of everyone, an average of male %26amp; female. I imagine male is a bit more, %26amp; female a bit less. so female, technically is 1/12.
