Explanation:
Detailed explanation-1: -Children look like combinations of their parents because they are. Each parent gives half of their genetic material to their children. Properties or traits are passed from parents to children and so on.
Detailed explanation-2: -Because relatives share family environment as well as heredity, familial resemblance can be due to environmental influences as well as to hereditary influences.
Detailed explanation-3: -Every child gets 50% of their genome from each parent, but it is always a different 50%. During meiosis, gametes get a random chromosome from each pair. This means that there are over 8 million possible DNA combinations from 23 chromosome sets!
