Question

In a group of dogs, some individuals have short fur and others have long fur. In this group,

the gene for the fur length trait has two alleles. The allele F is for short fur, and the allele f is
for long fur.
Clue, a dog from this group, has long fur. Clue has two alleles for long fur.
Based on this information, what is Clue's genotype for the fur length gene?

A) short fur
Bl long fur
C) FF
D) ff​

Answer 1

Clue's genotype for the fur length gene is 'ff' as long fur is a recessive trait, indicated by two lowercase 'f' alleles.

Step-by-step explanation:

Given that Clue, a dog from the group, has long fur and it is stated that he has two alleles for long fur, we can determine Clue's genotype for the fur length gene. In genetics, alleles for dominant traits are typically denoted with uppercase letters, while those for recessive traits are indicated with lowercase letters. Since long fur is a trait expressed when two alleles are present, it suggests that it is a recessive trait, thus we would use the lowercase letter 'f' to denote this allele.

Because Clue has long fur and must have two alleles for this trait, this means that Clue's genotype must consist of two recessive alleles. Therefore, the correct answer for Clue's genotype for the fur length gene is ff.

Answer 2

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.
