Study #1: PATN1 + LPP1/LPP2

This study looks at how LPP1 and LPP2 interact with PATN1 when Varnish Promoters are present, and Darkening Genes are added.

It appears PATN1's default state is a Blanket over the hips, and LP Promoter helps it spread across the body

Final Observations

  1. If LPP2 is present, Spot Size remains smaller regardless of LPP1 or not.
  2. Each time LPP2 was present with Homozygous PATN1, the result was a true Leopard Phenotype (i.g., visual appearance). 
  3. LPP2 Spreads Blanket Markings further than LPP1, in the presence of PATN1. 
  4. LPP1 Produces larger Spots than LPP2.
