Variance of gametic diversity and its application in selection programs
(Elsevier B.V., 2019-06-01)
The variance of gametic diversity (sigma(2)(gamete)) can be used to find individuals that more likely produce progeny with extreme breeding values. The aim of this study was to obtain this variance for individuals from ...
Ultrastructure of mature male gametes of Nitella hyalina (Charales, Charophyta)
(International Phycological Society, 2019-04-23)
This article describes the ultrastructure of male gametes of Nitella hyalina. Microtubular roots did not surround mitochondria completely. The number of microtubules varied from 12 to19 at the level of mitochondria, from ...
Segregation for Sexual Seed Production in Paspalum as Directed by Male Gametes of Apomictic Triploid Plants
(Oxford University Press, 2007-09)
Background and Aims: Gametophytic apomixis is regularly associated with polyploidy. It has been hypothesized that apomixis is not present in diploid plants because of a pleiotropic lethal effect associated with monoploid ...

Selection of cryoprotectants based on their toxic effects on oyster gametes and embryos
(2005)
Cryopreservation is a valuable tool for aquaculture by providing continuous seed production, regardless of the spawning seasons. This study aimed to select the least toxic among the cryoprotectants dimethyl sulfoxide ...
