oleracea, a rodent, has an odd diploid number of chromosomes (2n = 29) in somatic and germ cells of males as well as in somatic cells of females. The odd element, which is constantly present in both sexes, is a member of a sex-chromosome complex, for it forms a characteristic sex ...

Diploid is a cell or organism that has paired chromosomes, one from each parent. In humans, cells other than human sex cells, are diploid and have23 pairs of chromosomes. Are gametes and Diploids the same? Gametes arehaploid cells, and each cell carries only one copy of each chromosome. ...
The presence of the extra chromosome, in each case, had not affected pairing behaviour, and the rye chromosome was always a univalent. The striking conclusion, which emerges from this examination of a number of haploids with abnormal genetic constitutions, is that meiosis in wheat seems to ...

Alteration of basic chromosome number by fusion-fission cycles. A complete chromosomal fusion-fission cycle is described for the first time. In the field bean, , this cycle probably started with a reversible fusion of t... I Schubert,R Rieger,J Fuchs - 《Cycles Genome》 被引量: 38发表: ...
Our results indicate that the male- determining element is fully capable of determining gender in the progeny of hybrids between different lineages. Specifically, males crossed with females or hermaphrodites always generate 1:1 male:female or male:hermaphrodite sex ratios, respectively, regardless of ...
This confirms that the male determines the offspring sex and that the Y factor is confined to the L genome, in both normal and LRR-rich populations. Although a number of apparent sons from R sperm were found, they derived from many different males and were always vastly outnumbered by ...
