Development of cytochalasin in B-induced tetraploid and diploid/tetraploid mosaic mouse embryos.
By subjecting ¥x (CBA x C57/BL) x A eggs at the time of 2nd cleavage to 10 /tg/ml of cytochalasin B (CB), tetraploidy was produced in 52 % of 2-cell eggs and 35 % of 3-cell eggs. 2n/4n mosaic embryos were produced from 2-, 3and 4-cell eggs and amounted to 20 % of all treated eggs. 80 % of tetraploid embryos developed in vitro into regular blastocysts with half the cell number of control diploid...
متن کاملTetraploid cells of enhanced green fluorescent protein transgenic mice in tetraploid/diploid-chimeric embryos.
We succeeded in noninvasively analyzing the distribution of tetraploid (4n) cells in tetraploid<-->diploid (4n<-->2n) chimeric embryos by using enhanced green fluorescent protein (EGFP) transgenic (Tg) mouse embryos. We also evaluated whether this technique of analyzing 4n-cells in EGFP Tg 4n<-->2n chimeric embryos could be used to determine which characteristics of 4n-cells cause the death of ...
متن کاملGenetic analysis of isozyme variants in diploid and tetraploid potatoes.
Genetic segregations for six enzyme-coding genes were studied in diploid and tetraploid progenies obtained from various Solanum species. The loci identified are Prx-2, Prx-3, Prx-5, Mdh-1, Pgi-1 and Sdh-1. Prx-2 and Prx-3 were found to be linked; alleles at these loci segregated concomitantly in most of the diploid progenies. The putative homologous loci in tomato, Prx-2 and Prx-3, have also be...
متن کاملCall degradation in diploid and tetraploid green toads
According to the ‘environmental selection’ hypothesis, the physical characteristics of environments influence the evolution of long-range acoustic signals by favouring those properties that decrease sound attenuation and distortion with distance. Different environments could favour different acoustic properties and therefore contribute to the intraand interspecific variation of calls. In the pr...
