The pearlscale's body...the way it's shaped, is it affected by the gene that produces pearlscales? Or, were they bred to be that rotund? Also, the way that crown pearlscales wens are shaped...does the same ''pearlscale'' gene affect them, making them look like a bubble? Or, were they bred that way?

they are breed to be like that hun. The nicer the pearls and crown the better they do in showing
