Santa= AA
Mrs Claus= aa
-----------------------
PARIENTAL: AA x aa
Gamets: A A x a a
F1: Aa ,Aa,Aa,Aa -100% good vision
Pariental 2: Aa x Aa
Gamets: A a x A a
F2: AA Aa Aa aa so we have here 75% good vision,25% bad vision which is 3:1
and we have 1 dominant homozygous,2 dominant heterozygous and 1 recessive homozygous,which is 1:2:1.
