homozygous means they're the same so if 
A is dominant
a is recessive

homozygous dominant would be AA
homozygous recessive would be aa

heterozygous means you have two different alleles
so essentially Aa

does that help you decide with confidence between B and C?

Gucchi · Answer

Okay, so C?

AZ · Answer

if it's homozygous, that means it's going to be the same allele twice

if it's heterozygous, you're going to have the dominant allele and the recessive allele

I gave examples of both in my earlier reply

Gucchi · Answer

Ohhh so it is B

R is dominant
