Answer: Just did the lesson on this, the answer is C.
Explanation:An allele is one of the possible forms of a gene. Most genes have two alleles, a dominant allele and a recessive allele. If an organism is heterozygous for that trait, or possesses one of each allele, then the dominant trait is expressed. ... So a gene is a particular region of your DNA that controls a specific trait.
An allele is defined as the version of a gene, which codes for a specific trait and is present on the same loci of the chromosome.
The correct option is:
Option C. A gene that causes a specific trait
The allele is one of the possible versions of the gene. An allele codes for a specific trait and is present in the same place at the chromosome. For example, a gene has two alleles, dominant and recessive.
The dominant allele is expressed, whereas the recessive alleles are masked by the dominant.
The height of the plant can be controlled by two alleles, such that tall height is regulated by dominant, whereas short height is due to recessive alleles.
Therefore, Option C is correct.
