The karyotypic characteristics of   chub, Squalius cephalus have been investigated by examining metaphase chromosomes spreads obtained from gill and kidney tissues. The fish used in the study were caught with fishing nets from Dumlu Stream, one of the main tributaries of the Karasu River. The live fish were transported to the laboratory,  kept in a well aerated aquarium before analysis and then...

The SJPL cell line was reported and described as an immortalized porcine lung epithelial cell line suitable for influenza virus replication by Seo et al. (5) and has been available to researchers through ATCC (American Type Culture Collection) cell depositary services (deposit date, 5 April 2001; assigned accession number, PTA-3256) following a material transfer agreement. Recent findings indic...

The diploid number 2n = 30 is a presumed synapomorphy of Dendropsophus Fitzinger, 1843, although a noticeable variation in the number of biarmed/telocentric chromosomes is observed in this genus. Such a variation suggests that several chromosomal rearrangements took place after the evolutionary origin of the hypothetical ancestral 30-chromosome karyotype; however, the inferred rearrangements re...

N 1.50-CHROMOSOME is a chromosome having two identical arms A (DARLINGTON 1939). Such chromosomes have been studied recently by RHOADES (1940) in Zea and by DARLINGTON (1940) in Fritillaria. It is also very probable that the extra chromosomes in secondary trisomics, such as the numerous types which have been found in Datura (BLAKESLEE and AVERY 1938) are true iso-chromosomes. The manner in whic...

Abstract. Fathurrahman F, Mardaleni, Krisianto A. 2023. Title Effect of colchicine mutagen on phenotype and genotype Vigna unguiculata var. Sesquipedalis the 7th generation. Biodiversitas 24: 1408-1416. The problem with long bean species is low diversity varieties, so obtaining them using chromosomal mutations was necessary. One ingredients used colchicine. aim this study to determine effective...

The chromosome number and karyotype analysis of male trees of Pistacia vera L. was investigated to determine the sex chromosomes. For karyological determination, root tips were obtained from in vitro derived shoots. Afterwards fifty plates of mitosis were used for the karyotyping, the five best metaphase plates were measured for karyotype analysis, karyogram and idiogram. The conclusions obtain...

human chromosomes in amnion cells and lymphocytes with normal karyotype and in lymphocytes with pathological karyotype (2n=47, +21) were compared as to their position in the metaphase. none of the collectives showed sex differences. measurement of the radial distances revealed more peripheral position of the majority of large chromosomes. the satellite-carrying chromosomes of the d group always...
