the dominant gene is not determined by mom or dad. its determined by whoever (could be either or both) has the dominant gene. not all genes over ride another gene though. codominance is possible which is where both dominant, different genes are expressed in different areas of the organism (fur color for example) in different concentrations (pink flower from red and white parent flowers is another example. what we see is the dominant red gene but since the white gene is also mixed in, our eyes see a lighter red color).

How is color blind inherited?
Males inherit the gene from their mothers.
What is and example of a gene?
An example of a gene would be the X and Y chromosomes carried by the father. If the father can pass either gene to his offspring to get either a girl or a boy.
What genetic defect is more common in older mothers?
Genetic defects also can take place when the egg or sperm are forming if the mother or father passes along some faulty gene material. This is more common in older mothers. The most common defect of this kind is Down syndrome
Because the gene for red-green color blindness is located on the X chromosome it is normally not possible for a?
Females are rarely colourblind because they have 2 X chromasomes. They would therefore have to have inherited the gene from both parents (X from the mother and X from the father). As males have only 1 X chromasome and there is no corresponding place on the Y chromasome for the matching allele (gene), men who inherit the gene on the X chromasome (from their mothers) are automatically colourblind.
What is the full name for DNA and what is a gene?
Deoxyribonucleic Acid A gene is made of proteins. It helps specify how a person looks, you inherit one from your mother and your father.
Does the red hair color have to be in the father side for the child to have red hair if the mothers side has that hair gene color?
You've basically answered your own question here. No, the red hair gene needn't be on the fathers side, since the mother already has it. The chances become greater if dad has that gene for the child to have red hair, but if the mothers side has the gene, then there is a 1/4 chance it will have red. If dad has it, then more than likely the child will have red hair.
What is mothers father called?
grand father ;)
What would be the color vision of children if their mom is colorblind and their dad is normal?
Colorblindness is a recessive, sex-linked trait, and the gene that causes it occurs on the X chromosome. For the mother to be colorblind, she must have two copies of the gene and be homozygous recessive. The father, on the other hand, can not have the gene, because he (as a male) only has one X chromosome. So, if we let Xc represent the recessive gene for colorblindness and Xn represent the normal gene, the the mother is XcXc and the father is XnY. All of their children will receive the recessive gene from their mother. In the males, this means that they will be colorblind, because the chromosome they get from their father will by the Y chromosome. The daughters, however, will get the Xn gene, which is dominant and will override the gene for colorblindness. Thus, all of the couple's sons will be colorblind, and none of their daughters will be.
How is color blind inherited?
Males inherit the gene from their mothers.
Why have mothers?
Mothers have eggs which the father fertilizes. Mothers are needed to nurse and educate the child.
How are you related to your mothers mothers fathers mothers father?

How Do Mothers Get Pregnant?
Mothers get pregnant by the father. The father and mother gets on top of each other and has s*x.

yes, because the woman carries the baldness gene. The son would most likely have the same hair patterns as the mothers male family members
What called mothers father?
Mother's father is called a grandpa.
