Inbreeding and inbreeding avoidance in wild giant pandas.

abstract：:House mice are extra-ordinary animals -extra-ordinary in the literal sense of that word. They are pests - but also a valued laboratory animal. They are generalized rodents - and successful in habitats from tundra to tropics and from sea-level to high altitudes. They have differentiated into a perplexity of taxa, yet d...
