*sigh* you asked for this.
They were numbered. The question was which one you'd fuck. A lot of people said "threesome with the dad and the youngest daughter" or "fuck every daughter while the dad licks my balls"
Red hair is indeed a recessive trait, the father has one allele for red hair and a dominant allele for dark hair. So it's entirely possible but not bloody likely that many times in a row. Assuming the chances are 50% each time, then over 4 daughters the chances are 6.2% (0.5^4 = 0.0625).
