is it 100% chance that the child will also have blue eyes and blond hair, or is it 90%, 80%, or what?

  1. There is no easy answer, considering that single-gene inheritance is not responsible for hair and eye colour. Also keep in mind that the child is inheriting only half of each parents information; therefore if both parents just carry recessive alleles of such information, the chances can be as little as 1/4 chance of having blond hair or blue eyes.

    Just go get a paternity test.


  2. 50%=the same,25%=blue ,25%=blond

  3. Both traits are recessives, one simple the other(?).

    I'd say the minimum chance is 25%, but it varies.

  4. It is high but not 100%.  

    We don't have enough info to answer for sure, because we have no idea if the parents are homozygous or heterozygoos for each of those traits.

    As far as the eyes, blue eyes are generally a recessive trait, which means that both parents are liklely homozygous for blue.  That makes a very high chance that the children will be too.  

  5. well those answers above are good, but brown hair and eyes are dominant genes.  So if there is any brown genes, there is a chance that they might show up in your baby

  6. Blue eyes are recessive, so if both parents have blue eyes then both carry the gene for "blue-ness" twice, therefore the child will be blue-eyed .

    Hair colour isn't determined quite the same way because it isn't one 'single' gene that is responsible, however if both parents are fair haired it is likely that the child will be too, but possibly not the same 'blondness' as the parents. Most people with blonde hair tend to darken as they get older and it's worth remembering that most women dye their hair and going blonde is very popular.
