Okay, I need help.

"If short hair (L) is dominant to long hair (l), then what fraction of the offspring produced by a cross of Llxll will be homozygous dominant?

a) 1/2
b) 1/4
c) 1/3
d) none (no change of this offspring)

The key says that it's d, but when I do the punnet square, I come out with 50% Homozygous dominant. What am I doing wrong? Or is the key incorrect?

No, none will be LL, which is homozygous dominant. 50percent will be heterogous dominant (Ll)
I read it wrong, phew. Thank you!
