Ya because  mothers ova and fathers sperm combine and form zygote we know that ova and sperm are single cell and each cell has nucleus and nucles has gentic information so both parents characteristics are seen
A baby has characters of both parents as the genes from both parents are transferred to the child.This happens because of DNA. From the 22 pairs of chromosomes half are transferred from mother and half from father . These characteristics or traits are called inherited traits because they came from our parents. This is the reason behind a child having both characteristics.
