A man or woman with AS or AC or SS or SC or CC (very rare) cannot marry each other, if they want to avoid SS or SC. They must marry a partner with AA, if they don’t want to born a child with Sickle call syndrome. If AS or AC marry each other, they have 25% chance of having a sickle child at every birth.

What type of genotype is CC? The CC genotype is often referred to as “homozygous normal,” meaning that both copies of the gene contain the “C” allele.

Hemoglobin C trait (Hb AC) is clinically silent. Hemoglobin C disease (Hb CC) is a mild disorder that generally does not cause any symptoms and is associated with a normal life expectancy.

CC = Hemoglobin C Disease. 5. Hemoglobin C Trait. A person who inherits a Hemoglobin A gene from one parent and a Hemoglobin C gene from the other parent, will have Hemoglobin C trait (AC).

Genotype generally remains constant from one environment to another, although occasional spontaneous mutations may occur which cause it to change. However, when the same genotype is subjected to different environments, it can produce a wide range of phenotypes.

Compatible genotypes for marriage are: That way you save your future children the worry about genotype compatibility. AA marries an AS. You’ll end up with kids with AA and AS which is good.

That means each child of these parents has a 1 in 8 chance to have a baby with an O- blood type. An A+ parent and an O+ parent can definitely have an O- child.

homozygous dominant

The most common of these pieces of advice is for carriers of the Sickle gene (AS, SS, SC) not to marry fellow carriers of the Sickle gene. Thus, people with AS, SS and SC genotype are advised to marry only people who have the AA genotype to avoid the possibility of having SS babies.

A woman’s blood group could influence her chances of getting pregnant, scientists have found. Those with blood type O may struggle to conceive due to a lower egg count and poorer egg quality, while those with blood group A seem to be more fertile.

AB

AB Blood Type Personality They tend to be creative and inquisitive and, interestingly, most geniuses are said to come from the AB group.

B

Angelina Jolie, also rh negative.

Famous Type B personalities: Leonardo DiCaprio, Paul McCartney or Jack Nicholson.

AB negative

What’s the rarest blood type?

• AB-negative (. 6 percent)
• B-negative (1.5 percent)
• AB-positive (3.4 percent)
• A-negative (6.3 percent)
• O-negative (6.6 percent)
• B-positive (8.5 percent)
• A-positive (35.7 percent)
• O-positive (37.4 percent)

Rh null

Famous Type O personalities: Queen Elizabeth II, John Lennon or Paul Newman.

O negative is the rarest of all types and this blood type has no antigens. This makes it possible for donated O negative blood to be used for transfusion for other blood types, but an individual who has O negative blood can only receive blood from other O negative donors.

However, the need for O negative blood is the highest because it is used most often during emergencies. The need for O+ is high because it is the most frequently occurring blood type (37% of the population). The universal red cell donor has Type O negative blood. The universal plasma donor has Type AB blood.

When a mother-to-be and father-to-be are not both positive or negative for Rh factor, it’s called Rh incompatibility. For example: If a woman who is Rh negative and a man who is Rh positive conceive a baby, the fetus may have Rh-positive blood, inherited from the father.
