My sister have type o blood. what did my parents own to be for her to win this blood type?
and what could my blood type be?
Answers:
Everybody recieves one gene for blood type from their father and one gene from their mother. For blood type everyone has a phenotype (their genes) and a genotype (genes that are expressed). The O gene is always recessive. The A and B genes are always dominate. Let's speak a person has a phenotype of AO. This means they adjectives and A gene from one parent and and O gene from the other parent. Since O is recessive is will not be expressed and this person will have type A blood. Now lest say this AO phenotype entity has kids with a BO person. The kids could be AB, AO, BO, or OO. Since A and B are both dominate both genes will be expressed and the blood type will be AB. The AO kid will own type A blood. The BO kid will have type B blood. The OO kid will have type O blood.
If you're still with me, very soon I can explain your question. You know your sister have type O blood. Since she is type O we know her phenotype is OO. Therefore, we know your mom gave her an O gene and your father give her another O gene. There isn't enough info to say for sure what your parents blood types are. The could be AO (type A) and AO (type A), BO (type B) and BO (type B), AO (type A) and BO (type B), AO (type A) and OO (type O), BO (type B) and OO (type 0), or OO (type O) and OO (type O). They only item for sure is that neither on of them are type AB. As for your blood type, it could be anything. Source(s): I have a bachelors degree in Medical Technology. I work within all parts of a hospital Clinical Laboratory, including Blood Bank.
The only blood type your parents could NOT be is AB. They could be A, B, or o blood type. Since the o blood type is recessive, both of your parents had to contribute an o allele to her. However, you can be A or B blood type and still hold the recessive allele to contribute to an offspring.
Based on your sister being o blood type, you can't know for certain what your blood type is. You could be A, B, AB, or o. Source(s): conservatory
