What are genes? How are they related to traits?

Genes are related to traits because they are handed down from past generations of both x & xy chromosomes. for example, the offspring that has the mother with blue eyes & the father with brown eyes ... since brown eyes is a dominant trait, the likelyhood of their offspring having brown eyes is higher. it's also in the DNA If both parents have the dominant trait of brown eyes, even tho 1 parent has the recessive trait of blue eyes ...

a gene is a unit of DNA that is usually located on a chromosome, they carry information that determine the traits, traits are characteristics inherited from your parents.
