What are genes, and how are they
related to inherited traits?
• Genes are parts of DNA that give instructions
to the cells for expressing traits. Each body
cell has two copies of the same gene – one
from each parent. These copies, or alleles,
may be the same, or they may be different.
The combination of alleles is called the
genotype.
