Diversity in diploid, tetraploid and mixed diploid-tetraploid populations of paspalum simplex
(Crop Science Society of America, 2013-07)
The tetraploid cytotype of Paspalum simplex has a wide geographical distribution and reproduces by apomixis, while the diploid grows in a restricted area in northern Argentina and behaves as cross-pollinated. The objective ...

Hybridity and autopolyploidy increase the expressivity of apospory in diploid Paspalum rufum
(Springer Wien, 2016-08)
Paspalum rufum Nees is a perennial grass that forms a multiploid complex. natural populations are composed mainly of diploid (2n = 2x = 20) and tetraploid(2n = 4x = 40) cytotypes. The diploid form is sexual and highly ...

Transcript levels of ten caste-related genes in adult diploid males of Melipona quadrifasciata (Hymenoptera, Apidae): a comparison with haploid males, queens and workers
(2011)
In Hymenoptera, homozygosity at the sex locus results in the production of diploid males. In social species, these pose a double burden by having low fitness and drawing resources normally spent for increasing the work ...
