How to determine hair and eye color for future baby??

Question

Does anyone know the ties between the mom and dad's hair and eye traits that will determine the traits of their future baby? For example, if the mom has wavy brown hair and that dad has frizzy black hair, what kind of hair will the baby have? Same goes for eye color. Is there a website that explains this ? Thanks

There is no definate way to determine what your baby will look like. You can come up with a rough guess, but only time will tell. I'll try to explain genetics in a nutshell for you...

Each trait has one dominant and one recessive gene. The dominant is the trait you see, and the recessive is essentially "hidden", but that trait could become dominant in the right combination. When the sperm and egg are formed, only half of your information is given, so when they join to make the baby, it once again has a full set of information with one dominant and one recessive gene per trait. Generally darker colors and curliness are dominant, but there is a possibility of recessive traits showing as dominant.

Take my husband and I for an example. Each of us had a mother with green/brown hazel eyes and a father with blue eyes. My mother and his father have straight blonde hair. My father and his mother have curly black hair. You would think my husband and I would be identical, each with curly dark hair and green/brown hazel eyes. Due to the split genetics and regrouping, I have straight blonde hair and green/gray hazel eyes. My husband has wavy blonde hair and blue eyes. Both of our children have wavy blonde hair, but one has blue eyes and the other green/gray hazel.

The best way you can guess is to look at the combinations that can be made from each of your parents' genetics. Here's a guideline for genetic dominance...

Brown (always dominant if present)
Green (dominant to blue, recessive to brown)
Blue (always recessive, has to have two blue traits to show)

I'm not sure how hazel comes into play.

For hair color...

Red or Black (not sure which is "most" dominant)
Brunette
Blonde (recessive)

Although hair is a bit tricky because of the variant shades in between and highlights, etc. They can blend instead of being definate dominant and recessive.

And the same applies to degree of curliness and texture, ranging from frizzy (dominant) to straight (recessive).

I know this is long, but I hope it helps to explain.

Answer 2

You can partially determine this by looking up which genes are dominant and which ones are recessive. For example darker coloured genes are usually dominant, so in this case the baby will probably have frizzy black hair. If one of the parents has brown eyes and the other has green, the baby will probably have brown eyes. There's always a possibility that the baby will inherit recessive characteristics but it's less likely. Just look up "dominant and recessive traits" on Google and you should be able to find out more.

Answer 3

im not sure about hair but
if you want ur baby to have blue eyes you need a boy AND the girl to have blue eyes if the mom has brown eyes then the baby will have brown eyes evan if the dad has blue eyes
same for green eyes to

Answer 4

it all has to do with dominant and recessive genes. brown hair an eyes(or dark colors) are dominant. blonde and blue and recessive.

Answer 5

you can't determine it becuase babies take genes not only from its parents, but its grandparents too. Also, the child generally gets more genetics from one parent than the other. Thus, "The child looks just like his/her mother/father."

Hope it helped :)

Answer 6

those things are determined by grandparents, take a look at them and you'll fiugre out.
