actualy it is possible.... if your parents are homozygous for their alleles, it is possible. that only 1 or 2 could be inherited, though the chance is very slim.

If both parents are blue eyes, the blue eye trait is recessive, meaning a Dominant allele can't be present for them to have blue eyes,This is the P Generation, the F1 generation would only produce blue eye'd babies... If the blue eyed baby married with someone else that has Homozygous (Same of both alleles,) BB x bb then all 4 of the F2 generation would be Brown Eyed Heterozygous (Bb). But if the F1 generation bb has children with a Heterozygous Brown eye, Bb x bb then 50% of the F2 generation would have Heterozygous Brown, and 50% will have Homozygous blue...

So, unless a mutagen is involved it's TECHNICALLY not possible. Please tell me how I am incorrect..

It's the only thing in school Science besides chemistry I did like.

wtf!?!? where were you when i needed help with this for my Bio 5 test?!?! i failed it because I kept forgetting the difference between homozygous and heterozygous

True thing. My father has brown eyes, but my mother has blue eyes. But me and my two sisters are blue eyed, despite brown normally being dominant. When my dad (who loves science) asked the doctor about this, he said that it was a rare case, and that the brown-eyes gen somehow had remained dormant inside of us.

Genetics.

Your father = Bb (heterozygous, Brown eyed)
Your mother = bb (homozygous, Blue eyed)

punnet square results = 50% - Bb. (heterozygous, Brown eyed)
50% - bb. (homozygous, Blue eyed)

You and your sisters had 50% chance to have blue eyes.

Thats just the simplified version that explains it isnt unlikely they all have blue eyes.
