Question

Eye color is a trait influenced by several genes. The OCA2 and HERC2 genes determine how much melanin pigment is produced in iris cells. More melanin leads to brown eyes. Less melanin leads to blue eyes. Complete the diagram by matching to correctly describe the relationship between the terms.

• [ Choose 1
genes

traits
proteins

DNA

I Choose J
A
B
C
D

Answer 1

To complete the diagram describing the relationship between the given terms (DNA, genes, proteins, and traits), the connections can be made as follows:

1. **DNA** → **Genes**: DNA is made up of sequences of nucleotides that form genes.

2. **Genes** → **Proteins**: Genes are segments of DNA that encode for proteins, which are responsible for carrying out functions in the body.

3. **Proteins** → **Traits**: Proteins can influence the physical characteristics (traits) of an organism, such as eye color.

4. **Traits** → **Genes**: Traits are expressed as a result of the functionality and regulation of genes.

So the completed relationships would look like this:

- A. DNA → B. Genes → C. Proteins → D. Traits

If you have specific options to choose from for I and J, please share them, and I can help you select the correct ones.
