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 ...
Variabilidade genética estimada entre diplóides de banana por meio de marcadores microssatélites.

Transcript levels of ten caste-related genes in adult diploid males of Melipona quadrifasciata (Hymenoptera, Apidae): a comparison with haploid males, queens and workers
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 ...
Diversity in diploid, tetraploid and mixed diploid-tetraploid populations of Paspalum simplex
(Crop Science Soc Amer, 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 ...
Gene copy number and differential gene expression in haploid and diploid males of the stingless bee, Melipona quadrifasciata
(SPRINGER BASEL AGBASEL, 2012)
Complementary sex determination in Hymenoptera implies that heterozygosity at the sex locus leads to the development of diploid females, whereas hemizygosity results in haploid males. Diploid males can arise through ...
