Sunglow Motley 10" male

This 10" 2020 Sunglow Motley male is currently eating frozen/thawed day-old pinky mice.  Both parents are Sunglow Motleys, one a Red Factor (RF) homozygote, while the other had only one of the paired RF gene copies (he is a RF heterozygote).  Hence, I judge this one to have only one of the paired RF gene copies.  If I'm wrong, he is a RF homozygote with both copies of the RF gene?   $161.00 plus $39.00 flat-rate overnight domestic shipping.
