Heredity is the innate tendency of offspring to resemble their parents. It is the passing on of traits or characteristics from one generation to the next through genes. The study of heredity is known as genetics.

Explanation:
• The process of heredity involves the transmission of genetic information from parents to offspring.
• The genetic information is stored in the DNA (deoxyribonucleic acid) present in the chromosomes.
• The DNA contains the instructions for the development and functioning of an organism.
• The traits or characteristics of an organism are determined by the genes present in the DNA.
• The genes are segments of DNA that code for a specific protein or trait.
• The different versions of a gene are called alleles.
• The alleles may be dominant or recessive, and they determine the expression of a trait.
• The dominant allele is expressed in the phenotype, while the recessive allele is only expressed when it is present in both copies.
• The process of meiosis ensures that each gamete (sperm or egg cell) receives one copy of each chromosome, resulting in genetic diversity.
• However, the offspring still inherit traits from their parents due to the presence of specific genes in the chromosomes.
• The study of heredity is important in understanding the inheritance of genetic disorders and the development of new treatments and therapies.
