Question

a version of a gene is called a(n) (1 point)
phenotype.
genotype.
gamete.
allele.

Explanation:

• Phenotype: Refers to the observable physical or biochemical characteristics of an organism, resulting from the interaction of its genotype with the environment. It is not a version of a gene.
• Genotype: Represents the genetic constitution of an organism. It is the set of genes an organism has, not a single version of a gene.
• Gamete: Is a reproductive cell (sperm or egg). It contains half the genetic material of a somatic cell but is not a version of a gene.
• Allele: An allele is one of two or more alternative forms of a gene that arise by mutation and are found at the same locus on a chromosome.

Answer:

allele.
