If two phenotypically normal tigers that are heterozygous at this locus are mated, what percentage of their offspring will be cross-eyed?

Answer 1

# 1/4#

If having crossed eyes is a recessive characteristic, then each parent would have one dominant gene for normal eyes and one recessive gene for the aberrant cross-eyed trait.

One-fourth of the progeny would exhibit two dominant traits and be considered 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.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
