Woah...thanks for the FAST reply. Are you sure about that Joon? Isn't it Aa Wxwx testcrossed?

oh oh oh yeah
hold on sec, bathroom

AaWW test crossed with aaww
Aa x aa = 1:1 ratio between dominant and recessive
WW x ww = all dominant
so 50:50 between color waxy and noncolor waxy

why isn't there WxWx? Sorry, i'm super dumb at genetics.

first of all, ignore x. We can just talk about W vs. w

WW x ww = Ww, Ww, Ww, Ww.
Since W is dominant over w, it will have W phenotype.
