Genetic material is passed on from parent to offspring from "summary" of NCERT Solutions - Biology for Class 12th by Dr. Madhurbhashini,Sargam Hans,Shanya Hans
The transmission of genetic material from one generation to the next is a fundamental process in biology. This transfer of genetic information ensures the continuity of life and the preservation of genetic traits from parent to offspring. The genetic material, which carries the instructions for the development and functioning of an organism, is passed on through the reproductive cells of the parents. During the process of reproduction, specialized cells called gametes are produced in the reproductive organs of the parents. These gametes, which include sperm in males and eggs in females, contain a unique combination of genetic material derived from the parents. When a sperm fertilizes an egg, the genetic material from both parents combines to form a new individual with a unique genetic makeup. The genetic material, also known as DNA, is organized into structures called chromosomes. These chromosomes carry the genes that determine the traits and characteristics of an organism. Each parent contributes half of their genetic material to the offspring, with one set of chromosomes coming from the mother and the other from the father. The process of genetic inheritance ensures that offspring inherit a combination of genetic traits from both parents. This genetic diversity allows for variation within a species and is essential for the survival and adaptation of organisms to changing environments. The transmission of genetic material from parent to offspring is a key aspect of heredity and evolution, shaping the characteristics of individuals and populations over time.
