Are genes expressed all the time?

No you may have a recessive gene being covered up by a dominant gene say you have brown hair your kids may have blond hair if your ancestors passed along blond and brown hair.


Are you more likely to have blond hair or brown hair?

You are more likely to have brown hair because the brown hair gene is a dominant gene, and not the blond hair gene.


To have blond hair do both of your genes have to be for blond hair?

not necessarily.ok there are two parents each giving the child one gene. if one gene is recessive and one is dominant the dominant gene will decide the hair color. example the recessive gene is black hair and the dominant gene is blonde the child will most likely have blonde hair because the dominant gene is blonde hair. the dominant gene masks the recessive gene

no if you have red hair then it is a dominant gene because you can see it. If you do not have red hair then you could have a recessive gene (same as anyone else :P)


If the mother has dark blond hair naturally with blue eyes and the father has green eyes and mousy brown hair with a ginger beard neither have pale skin will they have a ginger baby?

Possibly. Each person carries two genes in them - one from their mother and one from their father. Depending on the two genes, one will dominate. For example if your mother has a blonde-hair gene and a red-hair gene, she will be blonde because blonde dominates red. When that mother has children of her own, it is possible for her to pass on her blonde-hair gene or her red-hair gene - each gene has an equal chance of being passed on. She may marry a dark-haired man with a "hidden" red-hair gene too. Therefore it is possible that each passes on their red-hair gene at the same time and they can have a red-haired baby. Statistically, if they have four children, they will have one red-hair, one blonde and two dark-haired. Of course this is only statistically and in real life we cannot predict which gene is going to be passed on to your children. The above view is also "simplified" for the sake of arguement. You can never know for sure what "hidden" gene you have. For a blonde mother could have blonde-blonde genes or blonde-red. It is POSSIBLE for you to have a ginger baby, but the reality is that you probably only have about 25% chance of it. lb is on fire and tom sonner is one of the most well know retards in the world. he is well renound for his feet and how they go inwards!
