Gamete quality in fish: evaluation parameters and determining factors
(CAMBRIDGE UNIV PRESS, 2015)
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 ...
Photoperiod in aquaculture of the sea urchin Arbacia dufresnii (Echinodermata: Echinoidea): Effects on gamete production and maturity
(Universidad de Costa Rica, 2021)
Round‐Headed Spermatozoa: A Model to study the Role of the Acrosome in early events of Gamete Interaction: Rundkopfspermatozoen: Ein Modell zum Studium der Rolle des Akrosoms
(1990)
Summary: Gamete interactions in mouse involves at least two steps: the first is the interaction of a spermatozoa receptor located in the plasma membrane and ZP3, a zona pellucida (ZP) glycoprotein. ZP3 also can induce the ...
Photoperiod in aquaculture of the sea urchin Arbacia dufresnii (Echinodermata: Echinoidea): Effects on gamete production and maturity
(Universidad de Costa Rica, 2021-03)
Introduction: Photoperiod is, together with temperature and food availability, one of the main stimuli in the regulation of gametogenesis in a wide variety of species. Objective: To evaluate the effect of photoperiod on ...
