Heredityessentially refers to the transmission of traits from parents to their offspring. This biological process is fundamental to understanding genetic inheritance and the diversity of life. Traits can range from physical characteristics like eye color and height to predispositions for certain diseases. The mechanisms of heredity are primarily governed by genes, which are segments of DNA located on chromosomes.

During reproduction, offspring receive a unique combination of genes from each parent. This genetic material determines their inherited characteristics. Genes come in different versions called alleles. When an individual inherits two different alleles for a particular gene, one allele may be dominant and mask the effect of the other, which is recessive. This principle, known as Mendelian inheritance, was first described by Gregor Mendel through his experiments with pea plants.

Beyond simple dominant and recessive patterns, heredity also involves more complex interactions. Some traits are influenced by multiple genes acting together, a phenomenon called polygenic inheritance. Environmental factors can also interact with genetic predispositions, influencing how certain traits are expressed. Understanding heredity is crucial in fields such as medicine, agriculture, and evolutionary biology, enabling us to predict disease risks, develop improved crops, and trace the evolutionary history of species.
