Question

4 multiple choice 1 point which of the following best defines an allele? a type of gene found in plants only the total number of chromosomes in a cell different versions of a gene the physical expression of a trait

Explanation:

An allele is defined as different versions of a gene. Alleles can code for different traits or variations of a trait. For example, in pea plants, there are alleles for different flower colors. It is not specific to plants (so option A is wrong), not related to the total number of chromosomes (option B is wrong), and the physical expression of a trait is the phenotype (option D is wrong).

Answer:

C. Different versions of a gene
