Reproduction, Genes, and Heredity
Genetic information is encoded in DNA molecules.
Item RH024005: Both a bird's physical characteristics and its behaviors could be affected by the information in the bird's DNA molecules.
Which of the following could be affected by the information in the DNA molecules of an organism such as a bird?
- Both the bird’s physical characteristics and its behaviors
- The bird’s physical characteristics but not its behaviors
- The bird’s behaviors but not its physical characteristics
- Neither the bird’s physical characteristics nor its behaviors

- Disciplinary Core Ideas
- LS3.A Genes are located in the chromosomes of cells, with each chromosome pair containing two variants of each of many distinct genes. Each distinct gene chiefly controls the production of specific proteins, which in turn affects the traits of the individual. Changes (mutations) to genes can result in changes to proteins, which can affect the structures and functions of the organism and thereby change traits.
- NRC Framework
- LS3.A In effect, proteins build an organism’s identifiable traits.
