PATHOLOGY

Detailed explanation-1: -Genetic information is passed from generation to generation through inherited units of chemical information (in most cases, genes). Organisms produce other similar organisms through sexual reproduction, which allows the line of genetic material to be maintained and generations to be linked.

Detailed explanation-2: -Humans can influence the inheritance of traits by selecting only parents that have desired traits through a process called selective breeding (also known as artificial selection). Technology can increase our ability to select and perpetuate helpful genetic traits in the plants and animals that provide our food.

Detailed explanation-3: -Basic techniques used in genetic material manipulation include extraction, gel electrophoresis, PCR, and blotting methods.

Detailed explanation-4: -In fact, selective breeding is one of the earliest forms of biotechnology, and it’s responsible for many of the plants and animals that we know today.
