A scientist studying fruit flies noticed that some had red eyes while others had white eyes. Which part of the fruit fly cell contains the information that determines eye color? Fruit flies inherit 

1        for red or white eyes, made up of 2          . Genes are located on 3           inherited from the parents, containing the genetic code for making the proteins that determine their traits.

The inheritance of genetic traits from parents to children follows predictable rules. Knowing that each parent contributes genes equally to each child, what determines an inherited trait such as eye color?

• Only the interaction between dominant genes.

• Only the interaction between recessive genes.

• The interaction between dominant and recessive genes.

• The interaction between dominant and recessive genes does not determine inherited traits.
