NEET BIOLOGY

Detailed explanation-1: -The inherited traits of an individual are determined by their genes. A single cell in the human body contains 25, 000 to 35, 000 genes. These genes carry the traits inherited by an individual from his parents. Gregor Mendel explained the concept of inherited traits in his experiments with the pea plant.

Detailed explanation-2: -The inheritance of each trait is determined by ‘factors’ (now known as genes) that are passed onto descendants. Individuals inherit one ‘factor’ from each parent for each trait. A trait may not show up in an individual but can still be passed onto the next generation.

Detailed explanation-3: -Definition. A trait, as related to genetics, is a specific characteristic of an individual. Traits can be determined by genes, environmental factors or by a combination of both.

Detailed explanation-4: -Almost all inherited features or traits are the products of complex interactions of numerous genes. However, the fact that there is no one genetic trigger has not by itself undermined the claim that many of our deepest character traits, dispositions and even opinions are genetically determined.

Detailed explanation-5: -The Roles of Nucleic Acids DNA, deoxyribonucleic acid, is the genetic material that is inherited from one generation to the next and is replicated whenever a cell divides so that all cells of an organism contain identical DNA.
