Hi, i have some doubts i would like to clear. What is the difference between codominance, incomplete dominance, and complete dominance?? i'm getting rather confused.

Question

What type of gene is the sickle cell anemia? Say r stands for the recessive allele for sickle cell anaemia, and R for normal allele, then a heterozygous person, Rr, would she just be a carrier without any sickle cell, or would she have less sickle cells than a homozygous recessive person, rr?

I'm rather confused about the blood type thing as well! (A, B, O and AB)

Please help! Thankyou
