Polyploid series occur but do not dominate the chromosome-number pattern. Secondary aneuploidy at polyploid levels is common. No single basic number has a really widespread systematic distribution in primitive by: In human genetics, a human Y-chromosome DNA haplogroup is a haplogroup defined by mutations in the non-recombining portions of DNA from the Y chromosome (called Y-DNA). Many people within a haplogroup share a type of mutation called single-nucleotide polymorphisms (SNPs).. The human Y-chromosome accumulates roughly two mutations per generation. Y-DNA haplogroups represent .   Chromosome and genetic status. Bamboo under the subfamily Bambusoideae is the giant member of grass family (Kigomo ).The basic chromosome number of most woody bamboo is 12 (x = 12), whereas in herbaceous bamboo it is 11 (x = 11) (Grass Phylogeny Working Group ).Two different polyploidy groups are present in woody by:

The results show that all these species have somatic chromosome numbers of 2 n = The absence of polyploids suggests that polyploidy may not have been a major driver of speciation and diversification of Berberis in the Nepal by: 2.

INTRODUCTION. The Asteraceae is the largest plant family (Bremer, ).Its many genera and species, its worldwide distribution and the fact that it comprises many useful plants have made it the subject of large numbers of karyological studies (Watanabe, and references therein).The Anthemideae, the principal focus of this study, is a medium-sized tribe in the family, with about Cited by: Full text Full text is available as a scanned copy of the original print version.

DAWSON Manaaki Whenua- Landcare Research P.O. Box 69 Lincoln, New Zealand Abstract Somatic chromosome numbers are docu- mented for 59 taxa, including three ornamental culti- vars, in 20 genera and 15 families from the New.

The flowering plants, also known as angiosperms, Angiospermae, or Magnoliophyta, are the most diverse group of land plants, with 64 orders, families, approximat known genera andknown species. Like gymnosperms, angiosperms are seed-producing are distinguished from gymnosperms by characteristics including flowers, endosperm within the seeds, Clade: Tracheophytes.

The list of organisms by chromosome count describes karotype, [2] [3] [4] and can be found by looking at the chromosomes through a ion is paid to their length, the position of the centromeres, banding pattern, any differences between the sex chromosomes, and any other physical characteristics.

[5] The preparation and study of karyotypes is part of cytogenetics. Krascheninnikovia is a genus of flowering plants in the subfamily Chenopodioideae of the amaranth family known generally as winterfat. They are known from Eurasia and western North America.

These are hairy perennials or small shrubs which may be monoecious or dioecious. They bear spike inflorescences of woolly : Amaranthaceae. Ravenala is a genus of flowering plants with a single species, Ravenala madagascariensis, commonly known as the traveller's tree, traveller's palm or East-West palm, from is not a true palm (family Arecaceae) but a member of a monocotyledonous flowering plant family, genus is closely related to the southern African genus Strelitzia and the South American genus Clade: Tracheophytes.

Pakistan lies on the postulated southern coastal route followed by anatomically modern H. sapiens out of Africa, and so may have been inhabited by modern humans as early as 60,–70, years ago. There is evidence of cave dwellers in Pakistan’s northwest frontier, but fossil evidence from the Paleolithic has been fragmentary (Hussain ).

The chromosome counts given for 45 non-hybrid species of aquatic monocots of Myanmar as well as well-investigated two Potamogeton hybrids among them were reviewed with a focus on infra-specific chromosome variation (Table (Table1).
