Thank you for this information. I was trying to know the meaning that made me to got into your post. We have similar issues, my fiance posted it on her status with another guy picture and I was like I must know the meaning. Thank you for this, it going a long way bro.

The knowledge of hemoglobin genotype is relevant when choosing a life partner to avoid compatibility issues that may result in devastating effects relating to conception. This is why it is essential to ask questions such as how many types of genotype are there and what is their compatibility.

People with sickle cells experience episodes of severe pains in body parts where oxygen flow is compromised because of blockage in the blood vessels. People with genotype AA are safe to marry individuals with any of the others. AS is compatible with AA, AS, and AS, AS and AC are too risky since two sickle cells should avoid conception. Below is a comprehensive compatibility chart:

AA + AA = AA, AA, AA, AA (Excellent)

AA + AS = AA, AS, AA, AS, (Good)

AA + SS = AS, AS, AS, AS, (Fair)

AA + AC = AA, AA, AA, AC. (Good)

AS + AS = AA, AS, AS, SS, (Very Bad)

AS + SS = AS, SS, SS, SS, (Very Bad)

AS + AC = AA, AC, AS,SS. (Bad; Advice needed)

SS + SS = SS, SS, SS, SS, (Very Bad)

AC + SS = AS, AS, SS, SS, (Very Bad)

AC + AC = AA, AC, AC, SS. ( Bad; Advice needed)

Difference between genotype and phenotype
Even though the two might sound the same and are related, they mean different things. While genotype refers to the set of genes in the DNA of an organism responsible for a particular trait, on the other hand,phenotype,is described as the physical expression, or characteristics of that trait. Phenotypes can be determined just by observing things such as height, hair color, and eye color, and so on.
