But deer all come into breeding readiness at the same time.
Brazilian Wood Stork colonies in the Pantanal have up to 10,728 birds breeding together at the same time [ 21], a situation favourable for EPC.
Herders favour piebald camels by selective breeding, but at the same time are aware of the risks of breed degradation and thus avoid inbreeding.9 As a result of the interplay between piebald genetics and selective breeding subjected to these two forces, the actual prevalence of piebald camels within a herd seems to be variable but seldom reaching the majority of the herds' camels (Figure 12).
Foster larvae were drawn at random from individuals breeding in the same batch and were formed into broods of either 5 larvae or 20 larvae.
Parents were always captured at burrows containing their offspring, and females were only detected breeding with the same male both within- and across seasons.
"Right now, we're breeding about the same number of pandas each year," Tang Chunxiang, an expert at the Wolong panda reserve, told the Associated Press.
For example, a recent analysis of two sympatric sister species in crater lake Xiloá found that, despite breeding in sympatry at the same depths and season, within both species the fishes paired highly color assortatively (95%% of A. sagittae pairs and 77 % of A. xiloaensis pairs were of the same color) [ 19].
The palolo worm exhibits unique breeding behaviour: during the breeding season, always at the same time of year and at a particular phase of the Moon, the worms break in half; the tail section (the "epitoke"), bearing reproductive cells, swims to the surface, where it releases eggs and sperm.
In short, identities of breeding partners were inferred from observations at feeding stations, and the genotypes of all offspring born in a given year were manually matched against all breeding pairs in the same year [18], [23].
