A. Such a mating would never occur in the wild, because of the two species' different ranges, and it is strongly opposed for several reasons by Mike Keel, the species survival plan coordinator for elephants of the American Zoo and Aquarium Association.
Dr. Carman hopes that the offspring of such a mating will get confusing signals about when to develop the egg, with the result that the plant will skip egg formation and produce an embryo with a full set of maternal chromosomes.
At Banstead Manor, when I spoke to managers in February, they were very positive about such a mating, and there are unlikely to be any practical problems about fitting in with southern hemisphere timings.
The probability for such a mating combination is highest if about half of the male population carry a t (hence ).
The conditions for the maintenance of such a mating system depend on the outcrossing rate of the open flowers, which can be estimated using neutral microsatellite markers.
When deleterious recessives have very low frequencies, the probability that a mating will be affected by more than one recessive locus and that such a mating will have a sufficiently extreme TBV to overcome the penalty, is extremely low.
However, because the immaculata morph specializes in sneak copulations with apparent adaptations for sperm competition [ 51], such a mating strategy would be successful only if sneaker males can circumvent pre-copulatory female choice, intrasexual aggression, or both (e.g.,[ 4, 5, 7].
You want to hug him, pat him on the shoulder, and say, "Stop being such a prat, mate".
Do I really deserve such a great mate?
Such a comparative mate sampling behaviour by females is described by Friedl & Klump [ 43] in the course of their field observations of H. arborea, whereby the females seemed to assess only a few males before they made their mating decision.
