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).

What does dominence mean?
Dominance refers to having power and control over others or a situation. In genetics, dominance refers to a gene that will be expressed and override the effects of a recessive gene.
What is and example of a gene?
An example of a gene is the BRCA1 gene, which is known for its role in hereditary breast and ovarian cancer. This gene provides instructions for making a protein that helps repair damaged DNA and maintain the stability of the cell's genetic material. Mutations in the BRCA1 gene can increase the risk of developing certain types of cancer.
What genetic defect is more common in older mothers?
Down syndrome is more common in babies born to older mothers due to the increased risk of errors in chromosome division during egg development. This leads to an extra copy of chromosome 21, resulting in the characteristic features of Down syndrome.
Can a o positive mother and o negative father have a b negative child?
Yes, it is possible for an O positive mother and an O negative father to have a B negative child. The child would have inherited one O gene from the mother and one O gene from the father, but could have received a B gene from each parent, resulting in a B blood type. The negative Rh factor would have also been inherited from the father.
Because the gene for red-green color blindness is located on the X chromosome it is normally not possible for a?
Because the gene for red-green color blindness is located on the X chromosome, it is more common in males, who have one X chromosome and one Y chromosome. Females have two X chromosomes, so they are less likely to inherit the gene from both parents.
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 ;)
Why have mothers?
Mothers have eggs which the father fertilizes. Mothers are needed to nurse and educate the child.
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 are you related to your mothers mothers fathers mothers father?
Your mother's husband is your father. His father-in-law is your mother's father, your grandfather. Your grandfather's son is your mother's brother, and your uncle. Your uncle's daughter is your first cousin.
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.
What called mothers father?
Mother's father is called a grandpa.
Is there a chance that a son will have ear hair and his father will not?
yes, because the woman carries the baldness gene. The son would most likely have the same hair patterns as the mothers male family members
