A) Describe the relationships among genes, DNA, and traits. (1 point)
Genes code for traits, which are composed of DNA.
Traits are made of genes, which are composed of DNA.
Traits are determined by genes, which are
composed of DNA.
The correct answer is allele. To determine this answer, we can break down the question. The question states that "A version of a gene is called a(n)." This indicates that we are looking for a term to describe different versions of genes. Let's consider each option:
1. Genotype: Genotype refers to the genetic makeup of an individual, including all the alleles they possess for a particular trait. It does not specifically refer to a version of a gene.
2. Phenotype: Phenotype refers to the observable traits or characteristics of an individual that are influenced by their genotype and the environment. While phenotype is related to genes, it does not specifically refer to a version of a gene.
3. Gamete: Gametes are reproductive cells (such as sperm and eggs) that join during fertilization to create a new individual. While gametes carry genetic information, they do not specifically represent different versions of a gene.
4. Allele: An allele is a specific version of a gene. Different alleles can exist for the same gene, which can result in different traits or characteristics being expressed. For example, the gene for eye color may have different alleles such as "brown" or "blue." Therefore, the correct answer is allele.
In summary, the correct answer is allele, as it refers to the specific versions of genes that can exist within a population.
