Addition of Genes

[Persol]

Question for all you biologists:
How does a species which has 10 chromosomes change to 11... and who does this new offspring breed with to produce the next generation. Does the offspring just take the whole extra chromosome from one of the parents?

 

[ElectricFetus]

One of the chromosome is duplicated, if the chromosomes duplication has no bad effects it will be passed on to the off-spring, unfortunately off-spring with odd chromosome counts and crossing-over mismatching would not be very viable with the rest of the species, the only solution to this is if the progeny inbreed with them selves

. I’m not a Geneticist though so that’s about as detail as I can get.
