Hello all,

I have a question that I'm working on for a college biologyassignment. My dad's mom and dad both have brown eyes, but all 3 oftheir children have blue eyes. I have no information on my greatgrandparents. I need to know what the genotype would be for eachindividual so it would be:

my dad's dad: brown eyes
my dad's mom: brown eyes
my dad: blue eyes
my aunt: blue eyes
my uncle: blue eyes

Here is the the specific wording on my assignment:
-If an individual in the family shows a recessive trait but theparents both show the dominant trait, what would be the genotypesof each individual?

I have done so much research and I am just not finding any info onthis. Most of the sites I go to say it is impossbile for 2 parentsto have brown eyes and the children all have blue eyes. If anyonecould help me on this, I would greatly appreciate it!!!!!

Thank you & have a good day!!!
