12th Zoology



Introduction and Scope

Genetics deals with various concepts and phenomena related to
inheritance. Mendel’s findings sowed the seeds for understanding the
secrets of heredity and paved the way for further knowledge on genes and
chromosomes. The post Mendelian period was remarkable in that many new
concepts and hypotheses related to general genetics such as factor (gene)
interactions, sex determination, linkage, sex linkage, crossing over, cytoplasmic
inheritance, multiple allelism polygenic inheritance were added.

The discovery of double helical DNA by Watson and Crick in 1953 has
unraveled the secrets of gene functions. The voluminous works on
Drosophila and prokaryotes like Escherichia coli opened up a new era of
modern (molecular) genetics. In modern genetics, human genetics
constitutes a part. It attempts to bring informations most important for
understanding the genetics of man who is also a species like any other
taxonomic species. Human genetics involves the identification of human
chromosomes; genetic engineering prospects; genetic diseases and gene
therapy; cloning devices; transgenic or genetically modified organisms etc.
Towards this line, the modern genetics also deals with the human genome
project; bioinformatics / biological data base and proteomics. (MODERN GENETICS)
