What are genes? how are they related to traits?

Explanation:

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..
