BikBok Posted June 2, 2010 Report Share Posted June 2, 2010 http://news.bbc.co.uk/2/hi/science_and_environment/10209169.stm I liked the guppies in the picture! But it's my delta tail red tux that performs the sneak matings while my wildtype male tries to show off with his pathetic little tail and does the whole shaking courtship thing. (but he is quite pretty in his own right!) Ohhhh, so that's why I have 3 kids..... :-? you're a fish?? Quote Link to comment Share on other sites More sharing options...
Dougstark Posted June 5, 2010 Report Share Posted June 5, 2010 Fertility can decline with intensive selective breeding and in-breeding. I had a drop off of clutch sizes after a few generations of selective breeding of show quality zebra finches. Quote Link to comment Share on other sites More sharing options...

BURN Posted June 6, 2010 Report Share Posted June 6, 2010 Inbreeding causes the problem or just bad selection for the inbreeding. You get more if not as many faults in out breeding then inbreeding and while you keep mixing and bringing in more faults by out breeding you should if inbreeding correctly be getting less faults being carried in your strains unless your selection is going towards the faults with your inbreeding then you get what your selection has inbreed to. Nature normally has no problem with inbreeding. Man dose not select for nature. Hahaha Quote Link to comment Share on other sites More sharing options...
raewyna Posted June 6, 2010 Report Share Posted June 6, 2010 That was interesting and seems to be new information. A few years ago I read a scientific book (came from Otago Uni I think) that had results of various experiments. Its conclusions were that female guppies take far more control over who they mate with than is usually apparent (eg the 'sneaks' don't usually succeed) and that they are usually only carrying offspring from 2 males at a time, sometimes three. Trouble is of course that the colours we like might not be the ones the females guppies like. Quote Link to comment Share on other sites More sharing options...
