Genetics

Explanation:

Genes are the stretch of DNA that code for a specific protein product. Genes are present in linear order on chromosomes and are carried from one generation to next via chromosomes.

Genes regulate the genetic traits and make the progeny and siblings have shared genetic traits. Shuffling of genes during sexual reproduction imparts certain new genetic traits to the progeny. This is the reason that the progeny of sexual reproduction is not genetically 100% identical to the parents.

The transmission of genes from parent to progeny, regulation of genetic traits by genes, heredity, and variations caused by genes are some of the aspects that are studied in genetics. Therefore, the study of structure, functions of genes and associated heredity and variations is called genetics.
