Are babies colour blind when they are first born?
Yes, newborn babies are not color blind, but they do have limited color perception. They are born with immature color vision and can only see contrasts between light and dark colors. Over time, their color vision develops and improves.
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?

Are babies blind and deaf at birth?

Do the parents have to be color blind in order for the kid to be color blind?
If the parent went blind due to an accident or a birth defect (born blind) then no. But if the parent has a disease that caused them to go blind then it is possible to inherit that as a child.
