Genetic variations are the genetic differences found among individuals of the same species. These variations are adaptive i.e. they ensure flexibility and survival of a population in the changing environment over time. It is quite interesting to know how and when these genetic variations offer to a population the survival benefit under the altered situations and at what extent over time. Whethe...

To delineate the contributions of genetic and environmental factors in the regulation of human prolactin (PRL) secretion, the 24-h profile of plasma PRL was obtained at 15-min intervals in 10 pairs of monozygotic and 10 pairs of dizygotic twins. Sleep was monitored polygraphically. PRL secretory rates were derived from plasma concentrations by deconvolution. Diurnal (24-h) variations were quant...

the genetic polymorphism of insulin-like growth factor binding protein ( igfbp-3 ) and its association with the growth traits namely condition factor, body weight, and total length were investigated in common carp cyprinus carpio using pcr- single strand conformation polymorphism (sscp) technique. caudal fin clips from 120 c. carpio , aging 5 months, were used in this study and a 330 bp dna fra...

Objective(s): Granular and lattice corneal dystrophies (GCDs & LCDs) are autosomal dominant inherited disorders of the cornea. Due to genetic heterogeneity and large genes, unraveling the mutation is challenging.Materials and Methods: Patients underwent comprehensive clinical examination, and targeted next-generation sequencing (NGS) was...

Aloe barbadensis is perennial, monocotyledonous, fleshy plant belongs to Aloaceae family. In this study, somoclonal variations of regenerated A. barbadensis plants were investigated. The plantlets of forth subculture transferred to the soil for further study. The genomic DNAs of 40 regenerated plantlets were extracted and genetic variations were studied using SPAR markers including RAPD and ISS...
