In tigers, a recessive allele causes an absence of
fur pigmentation (a "white tiger") and a cross-eyed condition. If
two phenotypically normal tigers that are heterozygous at this locus
are mated, what percentage of their offspring will be cross-eyed?
What percentage will be white?
Using the Punnett square below
where P = normal pigmenation and p = white
then 25% will be white (pp) and
all of the white offspring will also be cross-eyed
