Evolution is change in the heritable characteristics of biological population over successive generation. Molecular evolution is change in the sequence of molecule of cell. Evolutionary genetics is study where how change in genes leads to change. Molecular markers have ability to detect genetic variation. TRENDS IN EVOLUTION
New species form by speciation, in which an ancestral population splits into two or more genetically distinct descendant populations. Speciation involves reproductive isolation of groups within the original population and accumulation of genetic differences between the two groups.

Polymorphism is most apparent when it affects a visible or behavioral phenotype, but is not at all restricted to such traits. R. Lewontin and J. Hubby, in 1966, undertook the first extensive analysis of protein polymorphisms in natural population of Drosophila pseudoobscura by subjecting extracts of individual flies to get electrophoresis and observing the rates of migration of various proteins, which represented 18 gene loci.
Taxonomy, floristic studies, biosystematics, classical taxonomy, and modern taxonomic advances; phylogenomics, phylogenetics, and biogeography, including phylogeography; and the description of well-documented new taxonomic taxa, monographs, and taxonomic revisions. It incorporates data from classical morphology (including both macro and micro morphology), molecular study, anatomy and ecology, distribution, molecular evolution, evolutionary development, population biology, conservation biology, evolutionary ecology, paleobiology, and related methods and theories in recent development in systematics and floristic studies.
The categorization and maintenance of species records is important for science and conservation. For identifying an individual species, typically scientists will first consider Biological Species Concept, then descent from common ancestry and genotypic and phenotypic cohesion. Species concepts are still subject to debate.

Adult cyclostomes are too specialized or too degenciative in many respect. It is probable that many adult characteristics are adaptations for parasitic mode of feeding. Some of their specialized features are SPECIALIZED AND DEGENERATED CHARACTERS OF CYCLOSTOMATES

The equation derived based on the Hardy Weinberg equilibrium concept is called the Hardy Weinberg law. In this particular equation, p is represented as the dominant allele’s frequency and q is the representation of the recessive allele’s frequency. This is explained with an example to conclude a Hardy Weinberg equation. Consider a single locus with the presence of only two alleles namely A and a.
MOLECULAR ORGANIZATION OF EUKARYOTIC CHROMOSOMES : The large human chromosome of humans contains 300 million base pairs. If it is in normal confirmation, it constitutes a chromosome over 10 cm in length.

Tumor suppressor genes and oncogenes are important regulatory genes which encode proteins regulating transitions in and out of the cell cycle and which also
A disease in which cells divide abnormally and destroy body tissues. Three classes of genes are responsible for the onset of cancer. First one is proto oncogene the normally promotes cell growth. After mutation proto-oncogene changes into oncogene whose products are excessively active in growth promotion.
A Taxonomic key is a device, which when properly constructed and used, enables a user to identify an organism.In lifesciences, an identification key is a printed or computer-aided device that aids the identification of biological entities, such as plants, animals, fossils, microorganisms, and pollen grains.How names are correctly established in the frame of bionomial nomenclature Which name must be used in case of name conflicts How scientific literature must cite names
There are still heroes in science. They are recognized because the issues and problems they chose to study became the issues and problems of a major field of research. They are also recognized because their insights and solutions are the ones that are tested and evaluated when new ideas and technologies become available. In the field of plant evolutionary biology, the hero is George Ledyard Stebbins. His first scientific publi- cation appeared in 1929 and has been followed by nearly 60 magnificent years of seminal ideas, proofs, and proposals that defined much of what was worth doing in plant biosystematics, evolution and biological conser- vation. His energy, enthusiasm and good humor (widely shared at many congresses and symposia in the 'Singalongs with Stebbins') made him a wonderful teacher for both undergraduates and graduate students. He is the mentor of several generations of botanists, plant geneticists and evo- lutionists. A brief biography and publication list were included in Topics in Plant Population Biology, edited by Otto T. Solbrig, Subodh Jain, George Johnson and Peter Raven (Columbia University Press, 1979) which resulted from a symposium held on the occasion of Ledyard Stebbins' 70th birthday. In this volume, population biology and physio- logical ecology received major attention particularly in relation to plant form and function.
