Answer:
Both parents must be heterozygous (i.e. have one dominant and one recessive allele, such as Ff).
Explanation:
To answer this question, let's recall which genotypes produce the dominant and recessive phenotypes. For this example, let F represent the dominant allele (for orange fur) and f represent the recessive allele (for white fur).
If a tiger has genotype FF, they will have orange fur since they have two dominant (orange) alleles. If a tiger has genotype ff, they will have white fur since they have two recessive (white) alleles. If a tiger has genotype Ff, they will have orange fur. Although they have one of each allele, the allele for orange fur is dominant over the allele for white fur, essentially masking its effect.
Thus, in order to have the recessive phenotype (white fur), the genotype of the tiger must be ff (i.e. they must have two recessive alleles). This means that the allele received from each parent MUST have been the recessive allele. Since both parents have orange fur, they must have at least one dominant allele. Therefore, you can conclude that the genotype of both parents is Ff (heterozygous).
