Answer:
A. Children receive chromosomes from both parents that carry genes for certain traits.
Step-by-step explanation:
A "chromosome" is a strand of DNA that carries the genes. Each chromosome contains plenty of genes. The chromosomes come in pair. A person's chromones are derived from his parents: half from his mother and another half from his father. So, this means that children receive chromosomes from both parents.
Just like chromosomes, genes also come in pair. Each parent passes a copy of their gene to each child. This then shapes the traits of their children.
