In this system, the sex of an individual is determined by a pair of sex chromosomes. Females have two of the same kind of sex chromosome (XX), and are called the homogametic sex. Males have two different kinds of sex chromosomes (XY), and are called the heterogametic sex.
What is my genotype?
In a nutshell: your genotype is your complete heritable genetic identity; the sum total of genes transmitted from parent to offspring. There are four hemoglobin genotypes (hemoglobin pairs/formations) in humans: AA, AS, SS and AC (uncommon). SS and AC are the abnormal genotypes or the sickle cells.
How do I know my genotype?
Sometimes a genetic test will give you your genotype. Sometimes you just need a bit of genetic luck in your family tree to figure it out. And sometimes you can tell the two genotypes apart just by looking at someone. An obvious way to figure out you genotype is to have a genetic test done.
