# 1/4#


Assuming that being cross eyed is a recessive trait each parent would have one gene for normal eyes that is dominant and one gene for the abnormal recessive trait for being cross eyed.

# 1/4 #of the offspring would have two dominate traits and would be normal.

# 1/2# of the offspring would be like their parents having one dominate normal trait and one recessive abnormal trait. The dominate trait will dominate and the off spring will be normal

# 1/4# of the offspring would be homogenesis for the abnormal trait and would be cross eyed.
