in this study, we examined the chromosome number, detailed male meiosis, microsporogenesis, pollen fertility and distribution of cytotypes of diplotaxis harra (forssk.) boiss. this is the first cytogenetic report of the taxon. the two of the populations scored now from regions of the central showed aneuploid (x = 14) meiotic chromosome count and one of the populations studied from the existed a...

kermani sheep breed is one of the major sheep breeds in iran, especially in kerman province for which no study has yet been carried out through y-chromosome specific microsatellite markers. throughout this study, amplification quality related to 17 bovine y-chromosome specific microsatellites was evaluated for the mentioned sheep breed. one hundred males and twenty females of non-related animal...

In section Dentati, the chromosome numbers were reported from only eight of 30 taxa. There is no chromosomal record relating to other 22 present study, it intended detect Dentati Chromosome 15 taxa obtained, 13 which for first time and two agreed with previous reports. 14 diploid 2x = one taxon was polyploid 4x 60. Polyploidy might have played a role in karyotype evolution genus. Although polyp...

erodium (geranaiceae) species are distributed in different habitats of iran. some species are of medicinal importance while some are well known weeds. there are no chromosome counts for erdoium species of iran. chromosome numbers are given for six taxa of erodium (geraniaceae) from iran: e. cicutarium (2n=36), e. ciconium(2n=18), e. malacoides (2n=20), e. moschatum (2n=20), e. neuradifolium (2n...

background: chromosomal disorders are the most common cause of first trimester spontaneous abortion. among the human chromosomes, chromosome no.9 was the most common structural chromosomal variant and it is not thought to be of any functional importance, which often considers as a normal variation in structural polymorphisms, nevertheless there are some studies which claim that there is an asso...
