Hey, I was just wondering something about recessives.

I was wondering you hear 50% het for clown etc, now does that mean that clowns are homozygous animals? Pretty much just like codoms in that way for instance: Fire's are het for BEL's, except they show a visual difference. But with recessives het's they don't have any kind of color change and appear normal just carrying the parents gene. But when you do get that visual change from combing the recessive hets say the clown, thats considered homozygous?
