How do dogs get colorblind?
They are born colorblind, they don't just become it.
Can your child receive ssi for being colorblind?
no
What is the probability that this couple will have a colorblind child?
Impossible to know without information about genes that the parents have. are the parents colorblind? etc.
Can you be born colorblind?
Yes
How do you have a colorblind son if neither parent is colorblind?
It is just the DNA lottery. If neither parent is colorblind that just means that one of them (or both of them) have recessive genes for colorblindness that happened to show up in this particular child.
What allele combination would will have a colorblind child?
carried on the x chromosome
How do you go colorblind?
You don't. It something you have to be born with.
How is colorblindness transferred from the parent to the child?
We know that if a father is colorblind and the mother is neither colorblind nor a carrier, then the sons will not be colorblind. So, using logic, that means that the father can't cause a son to become colorblind. Process of elimination would point towards whenever a son is colorblind that it comes from the mother. A diagram explaining how colorblindness is inherited can be viewed in the related links.
Can two persons with normal vision produce a colorblind son?
No they will produce a child who is colour blind.
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.
If Couples that have normal vision what is the probability of them having a color blind daughter and color blind son?
It depends on a number of different factors. If colorblind is common in either family but the mother/father were lucky enough not to get it, then its a recessive gene. but if its not common in either family then its a very low chance the child will be color blind. Although, if there are numerous people on both sides of the family the probability is very high. It all depends on a lot of different factors. How dominant is the gene? How many relatives are colorblind? If there are any, and they have children, are they colorblind? The easiest way to figure out if the child will be colorblind is to have the kid and test it for colorblind-ness.
How often is a child born?
Each 2 seconds.
