Inherited traits are traits that you get from your parents that are influenced by your genes. Environmental
traits are influenced by your environment (you can learn them or control them).
2) List 3 examples of inherited traits. Explain why these traits are inherited traits.
Natural hair color, natural eye color, dimples, height, tongue roll, etc. These traits are inherited traits
because they are traits that are passed down from parents and are coded for by your DNA instructions.
3) List 3 examples of environmental traits. Explain why these traits are environmental traits.
Favorite music, good basketball player, language you speak, etc. These traits are environmental traits
because they are traits that you choose or learn or that are influenced by the place you live.

5) Fill out the following diagram with the words: Chromosomes, DNA, Alleles, Genes, Alleles (alleles is used
twice). The largest structure should label the largest circle
