Could my kids have blue eyes?

Question

My mums family are a mixture of brown and blue , however my mum has brown eyes and her mum and dad have brown eyes and my grans got brown and my grandad and then goes into blues/browns from there on..my dad and his family all have blue ..although I have brown eyes but i guess i still have the blue gene ye? does that mean even though brown is the more dominant colour that I could still have a good chance of a blue eyed baby of my own?

Answer 1

yes there is a chance.......

Answer 2

depends on their fathers eyes

Answer 3

Yes.

I have brown eyes and both my children have blue eyes.

I definitely carry the recessive gene (my mother had blue eyes, and my father has brown eyes)

My genes can be represented as Bb and my husband and his family all have blue eyes - represented as bb

Bb (brown with recessive blue) and bb (blue)

possible combinations:

Bb (brown) Bb (brown) bb (blue) bb (blue)

which give a 50% chance of having blue eyed children

Even if you have a partner with brown eyes, so long as he carries the recessive blue gene, then you would have a one in four chance of having a blue eyed baby.

Answer 4

well your family are only half of the gene pool your kids are from so yes your child could have blue eyes

Answer 5

If you want to you can genetically altar it (eye colour, hair colour etc). But I think that's wrong!

Answer 6

yes there is a good chance that they will have blue eyes-you might have to wait and see though because all babies have blue eyes when they're born. i mean it happens with hair colour to-both my parents have black/dark brown hair but i have blondy hair because one of my grandads had it.

Answer 7

If your dad has blue eyes, you must be carrying a recessive blue gene (plus the dominant gene for brown).  So it would all depend on what your baby's other parent had.

If he had blue eyes, you would be about 50% likely to have a blue-eyed child.

If he had brown eyes, but one of his parents had blue eyes, then he'd have to be carrying the recessive blue gene -- just like you -- so you would have about a 25% chance of having a blue-eyed child.  

If he and his parents had brown eyes, but one or two of his grandparents had blue, your chances of a blue-eyed baby would be about 12.5% or 6.25% (the lower number if only one grandparent had blue eyes).

A basic way to figure out the posibilities is to use what's called a Punnett Square (see the source link below).

Answer 8

Both my cousins (boy and girl) have blue eyes, both parents have dark brown eyes, but both grandfathers had blue eyes, so as long as somebody previously had blue eyes along the line, their descendants can have them too even if their parents don't.

Answer 9

Yesss, Unless your boyfriend/husband is carring a full brown gene. eventually blue will come around again and its sounding like it might be your child. : )

Answer 10

yep

Answer 11

If your partner has blue eyes, then that increases your chances of a blue-eyed baby. But you are right, the brown-eyed gene is dominant, so the probability is high for brown eyes.

My Mum and Dad have brown eyes, as did their parents, but my youngest brother has green eyes. Go figure. :)

Answer 12

it depends on the colour of the father of your childs eyes too.  if he has brown eyes it is relatively unlikely, if he has blue then yes, very likely.

i have green eyes and no one else in my family does, except my gran but hers are blue-green.  my mum has hazel and my dads are brown, the genetic mix resulted in mine being true green.
