Father isn't colorblind mother is a carrier--one son is colorblind but the other is not how?
If the mother is a carrier of the colorblind gene and the father is not colorblind, there is a 50% chance that each son will inherit the colorblind gene. It is possible for one son to inherit the gene and be colorblind while the other son does not inherit the gene and is not colorblind. This is due to the random process of genetic inheritance.
Does your eye color effect the Way you see things?
Highly unlikely. Eye color and color blindness are not determined the same way within your DNA. -Eye color depends on what color your eyes your parents have and the dominance of specific traits and alleles. -Color blindness is linked primarily to gender. It's a sex linked mutation and occurs only on the X chromosome. Males are much more likely to be color blind than females, because it is linked only to the x chromosome. Males only have one x chromosome and females have two. For females to have the colorblind mutation, their father has to be colorblind and their mother has to be a carrier or colorblind. For a male to be colorblind their mother has to either be a carrier or color blind. It is much more likely that mother is carrier than colorblind.
The family tree below shows the trait a colorblind The family tree below shows a trait a colorblindness. The only unknown is the father in the first generation what must be true about the father?
She has at least one recessive color blindness allele {apex}
What famous person is colorblind?
the first person that had color blindness was Mike Lion
In humans normal color vision is dominant over colorblindness. A colorblind male marries a female who is a carrier for color blindness. What is the probability that a colorblind child would be born to?
The probability of a colorblind child being born is 50%. This is because the male passes his Y chromosome to all his sons, and since he is colorblind, his sons will inherit the colorblind gene from him. The daughters will inherit their X chromosome from the mother and have a 50% chance of being carriers like her.
Is color blindness a carrier?
yes probably
If a color blind man has a color blind daughter then the mother has to be color blind as well?
The father has to be colorblind for the daughter to be colorblind because both X chromosomes must have the colorblindness gene in females because the colorblind gene is recessive. If only the mother is color deficient, then she merely passes on the gene to one of the X chromosomes in a female. If both the mother and father are both colorblind, then both X chromosomes in the female are effected and the female is colorblind. There are two scenarios in which a daughter may be born colorblind. 1. The father is colorblind and the mother is a carrier of the colorblind gene. The daughter will be either colorblind or a carrier of the colorblind gene. 2. The father and mother are both colorblind. If this is the case, then all of the children will be born colorblind.
What are the three interesting facts about color blindness?
1) Rats are the only mammals that can only see shades of gray 2)People with green red color blindness can spot out things that are camo than people that aren't colorblind 3)Dogs aren't colorblind
What type of color blindness is most common?
The most co on type of colorblindness is red-green colorblind.
What must be true about the father?
he is color-blind
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.
Can a colorblind father and normal sighted homozygous mother produce a daughter that is a carrier?
Color blindness is an X-linked trait. That means it is carried in the X chromosome, which differentiates whether a baby will be a girl or a boy. Women have two X chromosomes (XX), and men have an XY combination. If a woman is a carrier for color blindness, only one of her chromosomes will be affected (we'll call it a little "x"), and for that reason she will not be colorblind. Men, on the other hand, only have one X chromosome, so any time they carry the colorblindness gene, they will be colorblind. A child inherits one chromosome from each parent. He/She will get an X chromosome from his/her mother, and an X from her father (if a girl) or a Y from his father (if a boy). So, If a woman is a carrier, Xx, and a man is normal, XY, they have several different chances for different offspring: XX (a normal girl) XY (a normal boy) Xx (a normal girl who carries the colorblindness gene) xY (a colorblind boy) The short answer is, that if a woman has a boy, he has a 50% chance of being colorblind.
