Genetic Variation of Six Azadirachta excelsa (Jacks) Jacobs Populations

Genetic Variation of Six Azadirachta excelsa (Jacks) Jacobs Populations

The study of the extent and pattern of genetic variation of six populations of Azadirachta excelsa (Jacks) Jacobs, i.e. Manong (Perak), Pokok Sena (Kedah), Sik (Kedah), FRIM (Selangor), Merchang (Terengganu) and Sg. Caru (Pahang) was carried out using starch gel electrophoresis. The analysis on eleven enzyme systems was found to be coded by 25 and 26 loci. The mean of observed heterozygosity ra...

Genetic Variation Within PoPulations

Seven microsatellite loci were used to develop multilocus genotypes for 49 individuals of Neotoma stephensi (Stephen’s woodrat) collected from nine sites in central and northern Arizona. Several statistical analyses were used to determine genetic structure, levels of genetic variability, and degree of relatedness. Structure analyses estimated two distinct groups within localities. The FST value...

The Natural Variation in Six Populations of Calendula officinalis L.: A Karyotype Study

In the current investigation, karyotype analysis and chromosome characteristics of six populations of Calendula officinalis L.(pot marigold) from Iran are studied. Results showed that all populations were diploid (2n= 2x= 32), and had symmetrical karyotypes composing mainly of metacentric and submetacentric chromosomes. The mean chromosome length ranged from 1.05 in Karaj to 1.50 μm in...

Mitochondrial DNA variation, genetic structure and demographic history of Iranian populations

In order to survey the evolutionary history and impact of historical events on the genetic structure of Iranian people, the HV2 region of 141 mtDNA sequences related to six Iranian populations were analyzed. Slight and non-significant FST distances among the Central-western Persian speaking populations of Iran testify to the common origin of these populations from one proto-population. Mismatch...
