Genomics

Genes are responsible for transmitting the characters located on the chromosomes from one individual to another across the generations. Genetics is the study of different genes that are involved in different functions. Genetics is a branch of biology that studies genes, genetic diversity, and heredity in living organisms. The genetic system consists of genetic notations, which is a system of signs and symbols. Genotype refers to the organism's genetic composition, and phenotype refers to the observable property of the organism.
