If the moms side of the family is95%brown eyed,and the father's side is77%green/hazel eyed,can the kid ....

Question

have brown eyes?What r the chances of the next child having green/hazel eyes?

Answer 1

You can't do a simple Punnett square on eye color traits in humans. Eye color is either a polygenic trait, which means it is controlled by more than one gene, or a codominant or incomplete dominant trait, which means the traits from both parents can "mix", so to speak (think white paint + red paint makes pink paint). I can't remember which at the moment and don't have my books here with me. Either way, you would have to know the exact genetic makeup of the mother and father (their genotypes) to know what the probability is.

Answer 2

Actually, it depend on the group this is based on... 95% of the moms side based on 100 people or based on 2 people...

and 77% based on 100 people or on 2 people...

or 50 people on each side?

And even if... the color of the eyes are based on 4 cromozones:
2 from the mother an 2 from the father...

when the mix is done, this is the possibilities:

mother = b,b =95%
father= g,g=77%

when one side is for example blue, an the other brown...
results possible are=
bl+bl + br+br = bl+bl, bl+br, br+bl, br+br

only 4 possibilities

but if parents are: bl+br, and bl+br, then brown would be the
color of the parents eyes, but yet, they woul have 1 chance
out of 4 possibilities that their child would have bleu eyes, even
if both parent have brown eyes...

In your case green and brown....

average 95 brown + 5%green?
and 77green + 23% brown?

so brown=95+23= 118%
green=77+5= 82%

so on 100= 59 brown, to 41 green

Also, the color brown has a stronger preominancy per studies
but, chances are out of 4 possibilyties
br+br=25%of118%, br+gr=25%of100%,gr+br=25%of100% and
gr+gr=25%of 82%

You may actually have a green eye child more likely 1 chance
out of 6 only approxymately, given the informations above...
but it may so happen to be the second child anyway...

Good luck......

Answer 3

Now that is quite a difficult thing to say since statistics such as "95% of one side of a family" does not show the movement of the alleles for eye color being transfered. Instead, it would be wiser to create a pedigree chart (located below).

However, even then it may be difficult to pin down the exact chances the offspring will have either eye color since the trait (eye color) is represented by many different genes which create many different results (e.g. blue eyes, brown eyes, hazel eyes, green eyes, light brown eyes, etc.)

Still, if this is an assignment, your best bet is using that link below and imitating a Pedigree Chart. If this isn't an assignment, it will not be as simple.

Answer 4

A definate YES. Provided hazel eyed Mr. Jones from nextdoor contributes another 100% to that kids genes so now it's an overwhelming 277%!! Hehe..

Answer 5

so what would happed is that your next child boy or girl would have brown eyes because on your mom side of the family is 95% brown.natrual instinct babe.and you can have a child by me lol.puls think on the positive side

Answer 6

It doesn't matter. Some kids have more of their mom's genes than their dad's and vice versa.

Answer 7

Use that punett square thing or whatever that no one cared about back in middle school.

Answer 8

one hazel and one green eye... happy?

Answer 9

who knows.. but thanks for the two points
