Question

A ___________ determines which variations will survive to reproduce and which won’t.

Answer 1

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)

What is heredity ?

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.
