Is it necessary to have one Caucasian parent to be Duffy positive?

Hello,

Welcome to icliniq.com.

Hi,

I am glad you chose icliniq for your medical-related queries.

I understand your concern and will try to help you with it.

Below are the answers to your questions according to my opinion.

1. No. To be Duffy-positive, it is not necessary to have one Caucasian parent. The American and African are usually Duffy negative or null type, but minority American African people might show Duffy positivity. So I have answered in that way.

2. You are Duffy positive African- American. So one of your parents might have positivity for Duffy. But your parent does not need to be of Caucasian origin.

3. If only one parent is Duffy positive, you can also be Duffy positive.

If you are looking for paternity checking, then it is better to do genetic testing. Duffy blood group determination is not conclusive in that manner.

Thank you.

Hi,

Welcome back to icliniq.com.

I do understand your concern.

Thanks for asking again.

Below are the answers to your questions in my opinion.

1. No, it does not mean you can have 100 % Caucasian (European) origin. You have a small chance of being American or African origin as well.

2. The exact percentage of origin cannot be predicted. But for the Duffy positive origin, there can be approximately 70 % chance of Caucasian and the remaining portion from American or African. However, the prediction of the exact percentage needs to be commented on.

3. You can have a 70 % chance of having Caucasian origin and remaining of African or American origin. If you have doubts regarding paternity, then a genetic study is recommended.

Hi,

Thanks for asking again.

Following is my opinion on your asked question.

1. The Duffy group can have two gene alleles, fy a and fy b.
2. So one gene might be acquired from one parent and another from a different parent.
3. However, as I understand, you have only one allele positive in a heterozygous manner.
4. So you can have the chance of acquiring all genes from one parent only rather than a racial mixture, in my opinion.
5. However, for determining the biological father or mother, molecular testing is ideal.

Hello, Following is my opinion for your asked question. I want to say you can have acquired whole genes either from Caucasian (70% chance) or from African American origin (30%chance) as total of 100% genetic makeup as far as Duffy group concerned. So as far as Duffy group concerned you can probably have acquired whole positive Duffy group genome from either Caucasian or totally from African American I am not saying you are having mixture of gene for Duffy blood group positivity. Hope your concern solved. Regards

Hello, Welcome back. Following is my answer for your asked question. You can have 70℅ chance of acquiring Duffy positive gene from Caucasian origin and 30% chance of acquiring gene from African American origin. I am not saying you have racial mixture. The chance of racial mixture is less in your case. I want to say that either you have gene for Duffy from Caucasian origin or from American African origin. Hope I have answered your question Let me know if I can assist you further Regards
