Folia Primatologica; International Journal of Primatology
|January 1, 1975
Summary
This study found significant genetic diversity in Presbytis entellus (common langur) blood proteins, unlike other leaf monkeys. This high heterogeneity in common langur populations offers insights into primate population genetics.
Area of Science:
- Primate genetics
- Molecular anthropology
- Zoology
Background:
- Leaf monkeys (Presbytis) are important models for primate evolution.
- Previous studies indicated low genetic variability in some leaf monkey species.
- Understanding genetic diversity is crucial for conservation and evolutionary studies.
Purpose of the Study:
- To investigate the genetic variability of blood proteins in Presbytis entellus.
- To compare the genetic heterogeneity of P. entellus with other leaf monkey species.
- To explore the implications of observed variability on population structure.
Main Methods:
- Electrophoretic analysis of blood proteins from 26 Presbytis entellus specimens.
- Examination of polymorphisms in complement component 3, vitamin D-binding protein, and various enzymes.
- Comparative analysis with existing data from Presbytis cristatus.
Main Results:
- High degree of polymorphism detected in P. entellus for multiple blood proteins, including complement component 3, vitamin D-binding protein, alpha1-antitrypsin, and several enzymes.
- Variable band strengths suggesting potential polymorphism observed for acid phosphatase and lactate dehydrogenase.
- No significant variation found in the analyzed P. cristatus sample.
Conclusions:
- Presbytis entellus exhibits substantial genetic heterogeneity in blood proteins, contrasting with findings in other leaf monkey species.
- The observed variability may be influenced by factors such as sample collection and population structure.
- This study highlights the importance of considering intraspecific genetic diversity in primate research.

01:25What is Population Genetics?
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.While some alleles of a given gene might be observed commonly, other variants...
02:31Synteny and Evolution
John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.
Around 80 million years ago, the human and mice lineages diverged from the common ancestor. During the course of evolution, the ancestral chromosome underwent...

01:05Single Nucleotide Polymorphisms-SNPs
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...
01:26Polymer Classification: Stereospecificity
Polymerization generates chiral centers along the entire backbone of a polymer chain. Accordingly, the stereochemistry of the substituent group has a significant effect on polymer properties. Polymers formed from monosubstituted alkene monomers feature chiral carbons at every alternate position in the polymer backbone. Relative to the predominant orientation of substituents at the adjacent chiral carbons, the polymer can exist in three different configurations: isotactic, syndiotactic, and...
01:21Factors Affecting Dissolution: Polymorphism, Amorphism and Pseudopolymorphism
Polymorphism refers to the existence of a drug substance in multiple crystalline forms, known as polymorphs. Recently, this term has been expanded to include solvates (forms containing a solvent), amorphous forms (non-crystalline forms), and desolvated solvates (forms from which the solvent has been removed).
Some polymorphic crystals possess lower aqueous solubility than their amorphous counterparts, leading to incomplete absorption. For instance, the oral suspension of Chloramphenicol, which...

01:27Principles of Pharmacogenetics: Types of Genetic Variants
The human genome is over 99.9% identical between individuals, yet genetic differences exist at millions of bases. The human genome contains approximately 3 million variant positions per individual, many of which are heterozygous, contributing to genetic diversity and individual traits. Genetic variations include single-nucleotide polymorphisms (SNPs), insertions, deletions, and copy number variations (CNVs).SNPs, the most common variation, involve single-base changes in DNA. These can be...
