What color eyes and hair will a baby most likely have if the mother has light brown hair and green eyes the father has black hair and dark brown eyes but grandmother has blond hair and blue eyes?

I am only going off 7th form bio here but in terms of the eye colour:

blue is the resessive gene. brown is dominant. Because the father's mum has blue eyes - he MAY be carrying the blue gene (but still has brown eyes showing as this is dominant).

It is possible for the baby to have blue eyes. This will happen if the baby gets the recessive blue gene from it's dad, and the recessive blue gene from it's mum as well (I'm pretty sure green eyes carry a blue gene).

BUT if it gets the brown eye gene from it's dad - then even if it gets the mum's blue/green gene - it will have brown eyes because brown is dominant over blue/green.

Don't know about hair colour sorry :)
