well here's a little of what i remember....
cat coat colour is sex linked. females = XX, males = XY
something being sex linked mean that it is on the X chromosome.
if a gene is recessive it needs 2 the same to be expressed.
tabbie cat colour is recessive on the X, needs to be there twice for it to happen.
boy cats can be tabbie if they have an extra X chromosome. so they would be XXY.? this is called klienfelters syndrome.? human men can get this too.? think in humans the men are taller than usual, and can be infertile, but its not a definite thing - so guess its the same for puddy cats!!!!!! they have smaller man bits too i think. they are men, but a little bit girly i guess.... higher voices as well.
crazyness!!!!!!!!!!!
hope that made a little sense and no one got too bored!!!!

oops - meant tortie, got carries away and they both start with t!!!!!!!!
