KARYOTYPIC STUDY OF TRIFOLIUM SPECIES AND CULTIVARS IN IRAN
Trifolium species and cultivars are considered important forage crops iran , growing throughout the country. The present article considered the karyotypic details of Trvulim taxa using multivariate statistical analysis. Taxa studied included: Trifolim restylinatum (six populations: Shazand, Soriyan, Kordestan, Harati, Enaj and Lordegan), T. repense, T, fragverm, T. prateme and T, alexandrin...
متن کاملFemale meiosis drives karyotypic evolution in mammals.
Speciation is often accompanied by changes in chromosomal number or form even though such changes significantly reduce the fertility of hybrid intermediates. We have addressed this evolutionary paradox by expanding the principle that nonrandom segregation of chromosomes takes place whenever human or mouse females are heterozygous carriers of Robertsonian translocations, a common form of chromos...
متن کاملKaryotypic Study and Chromosome Evolution in Some Iranian Local Onion Populations
Abstract A karyotypic study was performed on 12 Iranian local onion (Allium cepa L.) populations. A number of mitotic cells at metaphase stage for each population were prepared. Chromosomes of suitable mitotic cells were counted and various parameters, including long arm (L), short arm (S), total length of chromosome (TL), relative length of chromosome (RL), arm ratio (AR), r-value, total chro...
متن کاملVariation in adult longevity in a polymorphic grasshopper species
Life-history theory suggests that the existence and persistence of phenotypic variation within species must be maintained through some advantage accruing to an individual following one developmental pathway over another. Here, we consider the adult lifespan of two highly differentiated male morphs and the female in the bladder grasshopper species Bullacris membracioides (Orthoptera: Pneumoroide...
