Heredity
The likelihood of a genetic variant being passed down to the following generation increases if a trait is favourable and aids the individual in surviving and procreating (a process known as natural selection)
<h3>What is heredity ?</h3>
The traits we inherit genetically from our parents and ancestors before them are referred to as hereditary traits. The possibility that you will have blue eyes is an example of heredity. Your likelihood of developing breast cancer based on family history is an illustration of heredity.
- DNA (deoxyribonucleic acid), which makes up genes, contains instructions for how cells should function as well as the traits that distinguish each individual. Each of your biological parents contribute half of your DNA to you, and you might inherit a gene mutation from one or both of them. Sometimes, problems with the DNA cause changes in the genes.

Answer:
Noble gases are the group 0 elements and are all considered as the unreactive non-metal gases. Their application relies upon their low density, inertness, and non-flammability. In comparison to other elements, the noble gases are inert, that is, they are excessively unreactive.
Generally, when the elements react, their atoms complete their outer shells by gaining, losing, or sharing electrons. The noble gases atoms already possess complete outer shells, thus, they do not possess the tendency to gain, lose, or share electrons. This is the main reason why noble gases are inert and are not involved in chemical reactions.
