Inheritance
आनुवंशिकता
Inheritance is the process through which traits are passed from parents to their offspring. In this Class 10 Science topic from the chapter Heredity and Evolution, students learn how genes located on chromosomes carry information, how alleles influence features, and how dominant and recessive traits are expressed. They explore Mendel’s experiments using pea plants, understand inherited traits and variations, and see how differences among organisms provide a foundation for studying evolution.
