What is the ratio of girls who are colour blind?
I don't know the ratio but I know that men are more likely to become colour blind because women have a backup gene.
What proportions of men and women are colourblind?
Xylophone
The gene for color blindness is a recessive allele located on the x chromosome. If a color blind man and color blind woman have one son and three daughters how many will be color blind?
Women can not be colorblind, only men. For questions like these a punnett square is useful. Men can not carry the colorblind trait, but women can. I know this is kind of confusing. When a carrier ( a woman with the color blind trait) has children with a man ( color blind or not) her kids will have 50% chance of having that trait. If its a girl, she will be the carrier. If its a boy, he will have the colorblind trait. SO TO ANSWER YOUR QUESTION: Theoreticaly, 1 of the daughters will be the carrier, and the son will have a 50% chance of being colorblind. Women can be colorblind, its just rare. About every 6400 women one is colour blind and with men, every 80 men 1 is colour blind.
Are blind men sexier to women?
maybe, maybe not but mostly NO
Does a blind man blinks his eyes?
Some do and some don't. Some blind men/women have their eyes completely shut, so they wouldn't have to blink. Some blind men/women have their eyes open, so they would usually blink.
Does colour blindness affect male and females equally?
AnswerWomen have the sex chromosomes XX, while men have the chromosomes XY. The gene for normal colour vision is found on the X-chromosome. If a woman has one X-chromosome with the gene and one without it, she will not be colour blind. On the other hand, a man with an X-chromosome that is missing the gene has no 'backup'. He will definitely be colour blind. Colour blind women have both X-chromosomes missing the colour vision gene. This is less probable mathematically than having just one X-chromosome missing the gene.
Why are men most likely to be color blind than women?
Men are not just 'likely' to be colour blind, they are the 'only ones' who can suffer from colour blindness. This is because colour blindness is cused by an x-linked recessive gene, that is it can occur only if a person carries 2 of these x-linked recessive traits. Now, females have one X and one Y chromosome,so in no way, they can have 2 X chromosomes.(exception-Klinefelter's syndrome, where thery is XXY trisomy) Only men can have 2 X-chromosomes. Hence, females can only carry the colour blindness gene, while men can 'suffer' from colour blindness.
Why do men choose ugly women over beautiful women?
Because they're stupid (and blind) !
Why cant women be color blind?
Women can be colour blind.AnswerI am a woman who is red--green colorblind. The trait is carried on the X chromosome. Males receive an X chromosome from their mother and a Y from their father. If the X carries the trait of colorblindness, the male will be colorblind. Females need to receive two defective X chromosomes to be colorblind, one from their father and one from their mother. If a women has only one defective X chromosome, she will be a carrier of the trait. My father was red-green colorblind and so was my mother's father, making my mother a carrier of the trait, although she is not colorblind herself. I have two sisters who are not colorblind, as they each received a non-defective X chromosome from my mother. I knew before my son was born that he would be red-green colorblind, as the X chromosome he received from me carried the trait.
Why Sexual transmmited disease are readily passed from male to women than from a women to man?
men and women are both passing the dissease in the same proportion. The difference is the men are most of the time asymptomatic while women are having symptoms and consulting in bigger proportions.
Is it normal for committed women to look at other men?
Of course. Committed isn't 'blind'.
What proportion of men and what proportion of women are affected by color blindness?
Colour vision deficiency (CVD) affects about 8% of men and 0.5% of women worldwide.
