re: RE: Re: Crossbreading? -Reply
I personally see no point in crossing to fish species/strains than
for any other reason than studying their "genetic" interaction.
Yes DNA analysis will give us an idea as to their relationship but it
still tells us nothing as we only use a small fraction of the
organisms genome for this analysis.
And since the deffinition for a specie still involves that the specie
should not be able to produce fertile offspring when crossed we have
to explore this this point. (Coincidently it is this point that is
spurring on the 1-or-2 species of discus debate that still wages on
Very true, but I believed that the defenition of species includes something
that states that such crossbreeding should happen under unforced
circumstances. What's unforced, when you put two sexes of different species
in a small tank in which they can't swim away from eachother and have no
choice but to mate to preserve their genes for next generations. Put the same
two species in a large pond containing individuals from both sexes, and the
cance on crossbreeds diminishes dramatically. Besides that, in nature they are
often not very likely to meet, so placing them together will always be a
And then you can still disagree with me, but then leave these experiments to
scientists, and don't allow just any hobbyist to crossbreed fish.
