Dear Dr. Rowell,
I read your interesting reply to Jamie Love's question about
chromosome 2 fusion in humans and the necessity, or lack of it, for
inbreeding to achieve successful mating. If there is no reproductive
barrier or reduction in fertility in many cases, then should it not
be rather common for a species to have variation in numbers of
chromosomes, just as there is variation in other heritable
characteristics that are not strongly selected against? But this
does not seem to be the case.
