Explanation: 

Detailed explanation-1: -The egg and sperm each have one half of a set of chromosomes. The egg and sperm together give the baby the full set of chromosomes. So, half the baby’s DNA comes from the mother and half comes from the father.

Detailed explanation-2: -Parents pass on traits or characteristics, such as eye colour and blood type, to their children through their genes. Some health conditions and diseases can be passed on genetically too. Sometimes, one characteristic has many different forms.

Detailed explanation-3: -Among the traits found most strongly determined by heredity were ambition, vulnerability to stress (neuroticism), leadership, risk-seeking, a sense of well-being and, surprisingly, respect for authority. The genetic factor for these traits was found to run somewhere in the region of 50 to 60 percent.
