Tetraploid/near-tetraploid acute promyelocytic leukaemia with double (15;17) translocation.
The Malaysian journal of pathology, 2021A 57-year-old man presented with intermittent fever and bleeding following dental surgery. Peripheral smear and bone marrow aspirate exhibited unusually large and bizarre-looking abnormal cells which were found to be myeloblasts with aberrant CD56 and CD2 expression on immunophenotyping.

First generation tetraploids were produced by hydrostatic pressure treatment before the first cleavage and raised until the adult stage. Their survival and growth were severely depressed when compared to the diploid control: after two years, no ovulated females were found although males produced sperm at 1 and 2 years of age and were mated individually

Plant breeders have been fascinated with doubling of chromosomes of plant species since the discovery of colchicine in 1937. The early research on doubling of chromosomes of red clover, conducted primarily by Swedish researchers, met with considerable success over the years, and continuing to the present, many tetraploid cultivars have been produced ...

There are well over a thousand races of Grain Sorghums under cultivation all over the world. Without an exception all of them are diploid with 2n = 20 chromosomes. Haploids and triploids have been reported as rare occurrents (Brown 1943; Price and Ross 1955). Under experimental conditions Chin (1946) by colchicine treatment produced autotetraploids and

Lathyrus odoratus has been classical material for genetic study ever since the rediscovery of Mendel's work. But up to now, no chromosomal aberrations of any kind have ever been found. The sweet pea, in common with all other species of Lathyrus hitherto investigated, has seven regular bivalents at meiosis. It is therefore of interest to report here the

A RECENT communication1 has suggested that among Hymenoptera Symphyta males may be diploid, females tetraploid. It was further suggested that this characteristic might help to explain the phenomena of pre-conjugation as seen in Apis and Cynips kollari.

TRIPLOID AND TETRAPLOID HYBRIDS FROM DIPLOID X TETRAPLOID CROSSES IN GRINDELIA (COMPOSITAE)
American Journal of Botany, 1970Crosses between the diploids G. oxylepis var. eligulata Steyermark (Mexico) and G. havardii Steyermark (New Mexico) and the tetraploid G. aphanactis Rydb. (New Mexico) were made. With G. aphanactis as the pistillate parent and G. havardii as the pollen parent a triploid hybrid was obtained in which the maximum meiotic configuration observed was 6m. The
