The correct answer is A because the absence of fur pigmentation is caused by a recessive allele that also causes the tigers to be cross-eyed. If two tigers heterozygous for this allele mate, 1/4 of the offspring will be homozygous recessive for the allele and will be both white and cross-eyed. 3/4 of the offspring will be heterozygous for the allele and will be orange with normal eyes.
