What else can I help you with?
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.
What is the probability of color blindness if the father is color blind and the mother carries the trait?
All daughters are normal, half the sons are color blind. The above answer is incorrect. Half of the daughters are color blind and half of the sons are color blind. Since the father always donates color blindness, it is up to the mother in each case (in the son's case, the father is irrelevant) to determine if the child is color blind or not. Since she is a carrier, the chance is 50-50.
A color-blind woman mates with a male with normal color vision Which of these results would indicate that color blindness is caused by an X-linked recessive allele?
If the couple has a color-blind son, it would indicate that color blindness is caused by an X-linked recessive allele. This is because sons inherit their single X chromosome from their mother, who carries the recessive allele for color blindness but does not express it due to her second X chromosome providing the normal color vision gene.
Are Crickets color blind?
Indeed they are color blind, they cannot see colors that humans can see. But they can see the ultraviolet rays of the sun, that us humans can see.
How do you know you are the color blind ones and the people who are color blind aren't?
Color blindness is determined by genetics and results from a specific gene mutation. Those who are color blind lack certain types of color receptors in their eyes, leading to difficulty differentiating between certain colors. This condition can be diagnosed through a series of tests performed by eye care professionals.
