Answer: D) ff
Explanation: Clue's genotype for fur length gene is ff. From the information given above, the allele for long fur is f and Clue has two alleles for long fur.
Since long fur allele is f and Clue has two long fur alleles, therefore clue's genotype for long fur is ff.
A genotype is a pair of gene that controls a particular trait. A gene appear in different forms known as alleles. Long fur trait in Clue is controlled by a pair of gene ff.
