Tetraploid development in the mouse [PDF]
Developmental Dynamics, 2003 AbstractSpontaneous duplication of the mammalian genome occurs in approximately 1% of fertilizations. Although one or more whole genome duplications are believed to have influenced vertebrate evolution, polyploidy of contemporary mammals is generally incompatible with normal development and function of all but a few tissues.

Genomics, Proteomics and Bioinformatics, 2013 Abstract The aim of this study was to optimize electrofusion conditions for generating porcine tetraploid (4n) embryos and produce tetraploid/diploid (4n/2n) chimeric embryos. Different electric field intensities were tested and 2 direct current (DC) pulses of 0.9 kV/cm for 30 μs was selected as the optimum condition for electrofusion of

Tetraploid Diœcious Melandrium
Nature, 1952IN 1942 I published a short note1 on a tetraploid plant of diœcious Melandrium found growing wild in Svalov in southern Sweden. The specimen in question was a female individual growing between the fields behind the place where the new laboratories of chemistry and cytology were erected later. Its flowers were red, as in M. diœcum ssp.

We collected and sequenced 203 accessions including 153 landraces and 50 improved cultivars, from 31 countries worldwide. These represent five botanical varieties [var. fastigiata (80), var. hypogaea (56), var. vulgaris (47), var. peruviana (11), and var. hirsuta (9)].

Theoretical and Applied Genetics, 1986
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

PRENATAL DIAGNOSIS OF A TETRAPLOID FETUS
Prenatal Diagnosis, 1997A tetraploid fetus with an unusual facial appearance and multiple congenital anomalies (large cerebral lateral ventricles; lung, cardiac, and genital abnormalities) is reported. Chromosome analysis was performed on amniocytes and fetal blood lymphocytes. A comparison is made with other reported cases (nine liveborn infants and one 17.2-week-old fetus).
