A species can produce offspring through different types of mating, such as random outcrossing, correlated outcrossing, biparental inbreeding, self-pollination, apomixes or a combination of these reproductive strategies.
In the second case, the outcrossing between two maize fields was modeled using equation discovery [5].
Phillips, "biologists going all the way back to Charles Darwin have been puzzled why sexual reproduction via outcrossing exists at all.
Outcrossing has outfoxed our ability to control it.
napus is capable of selfing and outcrossing, having an outcrossing frequency of 20-30%.
Burrows says these results suggest that the yellow box, like other eucalypts, has a mixed mating-breeding system with preferential outcrossing (pollen exchanged between different trees), but also is capable of self-pollination.
Germination frequency and seedling mass was consistently higher in progeny resulting from outcrossing than those from selfing, and cumulative inbreeding depression was estimated to be 0.
In two different models, Holsinger (1986) and Ronfort and Couvet (1995) studied the maintenance of intermediate outcrossing rates in structured populations with seed dispersal among subpopulations, and J.
Whether a species is self-pollinating or outcrossing makes a difference in genetic variability.
However, the offspring that result from outcrossing generally grow bigger and faster and reproduce more often.
