Define heredity as the passage of genetic instructions from one generation to the next generation.

Heredity is a biological process which involves passing of genetic information from parent to their offsprings. The genetic information is in the form of genes which are transmitted from parents to their offsprings by the mode of asexual and sexual reproduction. A gene is a basic physical and functional unit of heredity. Genes contains the genetic codes or sequences of nucleotides bases for the production of specific proteins. Hence, genes are expressed in the form of proteins to develop genotypic and phenotypic traits similar to parent in a offspring. This proves that heredity is the passage of genetic instructions from one generation to the next generation.

Heredity is a biological phenomenon that involves transfer of genetic information from parents to their next generation that is to their offsprings. The genetic information is transferred through genes, which are the basic unit of heredity. In simple terms heredity reflects the inheritance of traits ( like skin tone, eye color) by children from their parents.

Genes are the segments of DNA that contain genetic instructions in the form of nucleotide sequences.

Thus, heredity is defined as the passage of genetic instructions from one generation to the next generation.
