One example of such research cited in the report was of animals being used in reproductive biology experiments as part of training for researchers.
Reproductive cloning experiments were performed for more than 40 years through the process of embryo splitting, in which a single early-stage two-cell embryo is manually divided into two individual cells and then grows as two identical embryos.
In fact, the results of the reproductive isolation experiments performed by Gómez and Serra [37] and Suatoni et al. [38] with the B. plicatilis species complex do not reveal a pattern of male discrimination between females belonging to the same and to a different clone within the same species.
Primer sequences:> In the chronic stress and reproductive success experiments, group differences in reproductive success, mating success, and pregnancy success were examined using G-statistics and Fisher's exact tests on raw numbers, not percentages.
With regard to postzygotic reproductive isolation, experiments with F2 backcrosses among Drosophila species have consistently demonstrated that hybrid sterility is attributable to genes on every arm of every chromosome [ 15].
Reproductive isolation experiments in B. plicatilis s. s. have shown a steady and significant decline of fertilization success at relatively low genetic distances of less than 8% COI divergence (Suatoni et al. unpublished manuscript).
Brachionus plicatilis s. s. is part of a relatively well-known species complex that is composed of more than a dozen species as elucidated by morphological, phylogenetic and reproductive isolation experiments [ 19, 21, 33].
Therefore, the purpose of this study was to isolate and characterize microsatellite loci in S. aurea to conduct reproductive biology experiments and to estimate the selfing rate in a progeny array, which will contribute to a better understanding of the functional role of diplostigmaty.
When the relationship between CMV multiplication and virulence (V) was analysed comparing all accessions and isolates together, no significant correlation was found between these traits, either when plants were infected at reproductive stage (Experiment 1) or at vegetative stage (Experiment 2) (P ≥ 0.25).
During the toxicity, reproductive, and regeneration experiments, any changes in animal behavior, skin color, and mucous production were registered on a daily basis.
