Detailed explanation-1: -How we inherit characteristics. 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-2: -Inherited traits are coded in our DNA and hence can be passed on to the next generation. Example: eye colour, height, complexion, hair colour etc. The variations that emerge as a result of reproduction may be inherited which causes an increase in the survival rate of entities.
Detailed explanation-3: -Genes carry the information that determines your traits (say: trates), which are features or characteristics that are passed on to you-or inherited-from your parents. Each cell in the human body contains about 25, 000 to 35, 000 genes.
Detailed explanation-4: -All organisms inherit the genetic information specifying their structure and function from their parents. Likewise, all cells arise from preexisting cells, so the genetic material must be replicated and passed from parent to progeny cell at each cell division.
