Hey Maya, I was just thinking about something interesting. What is your blood type? |
|
|
Oh, hey David! Yeah, I'm type A. Why do you ask? |
|
|
Well, I heard this theory that your blood type is somehow related to your personality, like Type A people are supposed to be more organized, and so the way, do you know how these blood types are made? |
|
|
Haha, yeah, but I don't think it's backed by any scientific evidence. It's more of a fun cultural thing. It's like saying people born in July are all introverts! By the way, do you know how these blood types are made? |
|
|
Well, the only scientific thing I know about blood types is that they're inherited from our parents. |
|
|
You're right! It's a combination of our parents' genes. Each person inherits one gene from each parent, and these genes determine their blood type. The one that determines our blood types, like A and B, is called ABO antigens. |
|
|
ABO antigens? Sounds complicated. |
|
|
Not really. The ABO system classifies blood into four types: A, B, AB, and O. The letters represent the two alleles inherited from each parent. For example, if you inherit an A allele from both parents, that means you are AA, and you'll have Type A blood. |
|
|
Okay, I think I can do that. So, if you inherit a B allele from one parent and an A allele from the other, that means you are Type AB. Is this right? |
|
|
Correct! And if you inherit an O allele from a parent, it remains hidden because it's a recessive allele. The presence of the dominant A or B allele will determine the blood type, resulting in either blood type A or B, respectively. |
|
|
I think now I understand how blood types are made. But anyway, what's the point of the classification if it's not related to the personality? |
|
|
Actually, blood typing is necessary for various medical and practical reasons. In medical emergencies, surgeries, or other situations where blood loss occurs, transfusions may be necessary. It's crucial to match the blood type of the donor and recipient to prevent an immune system reaction. |
|
|
Oh, I got it. It has more serious implications than I thought. Knowing your blood type is crucial, not for personality but for life! I'll definitely look at blood types in a whole new way now. |
|
|
That's great news to hear! |
