Karyotype evolution in progress: A new diploid number in Belostoma candidulum (Heteroptera: Belostomatidae) from Argentina leading to new insights into its ecology and evolution
(Czech Academy of Sciences, 2014-05)
A novel chromosome complement (2n = 14 = 12 + XY/XX; male/female sex chromosomes), male meiosis behaviour, heterochromatin characterization, and frequency and distribution of chiasmata are described for the first time in ...
Meiotic segregation and interchromosomal effect in the sperm of a double translocation carrier: a case report
(2009)
Abstract
Background
Infertility is a natural mechanism of selection intended to prevent the delivery of a child with malformations or mental retardation. Male infertility is closely related to chromosomal ...

Genome size and climate segregation suggest distinct colonization histories of an orchid species from Neotropical high-elevation rocky complexes
(Oxford Univ Press, 2018-07-01)
Knowledge about the geographical distribution of cytotypes is crucial to understand the role of polyploidy in diversification. High-elevation rocky complexes (HERCs) are heterogeneous formations found in elevated areas of ...
Robertsonian chromosome polymorphism of Akodon molinae (Rodentia: Sigmodontinae): analysis of trivalents in meiotic prophase
(Sociedad de Biología de Chile, 2001)
First report of B chromosomes in three neotropical thorny catfishes (Siluriformes, Doradidae)
(Pensoft, 2017-01-09)
The family Doradidae (Siluriformes) is an important group of fishes endemic to freshwater ecosystems in South America. Some cytogenetic studies have been conducted focused on the group; however, there are no reports on the ...
Meiotic behaviour and B chromosomes in Argentine populations of Chrysolaena verbascifolia (Vernonieae: Asteraceae)
(Taylor and Francis Ltd., 2017-01)
Four populations of Chrysolaena verbascifolia (Vernonieae: Asteraceae) from localities in Argentina were cytologically analysed for meiotic behaviour and pollen viability. This is the first meiotic analysis in the species. ...
