In a cross between two Bb individuals how many of four offspring will have blue eyes?

Question

4

2

1

3

Answer 1

This is a vast oversimplification because eye colour isn't controlled by a single gene.

If you do go with the high school simplification of brown being dominant and blue being recessive then the answer is 1, as previously stated.

Answer 2

lighter is recessive almost always=/ isnt that funny... all of them could have blue eyes possibly though=/  but the probability of 1 child to have blue eyes is 25% so out of 4 children, 1 should.

Answer 3

If I remember correctly,  Bb is Brown with recessive blue.  BB is dominant brown and bb is pure blue.

the out come is

      B      b

B   BB  Bb

b   Bb    bb

So the Prabability of having a blue eyed offspring is one in four.
