If someone with thalassemia trait were to donate blood, would the recipients of that blood be carriers?

No: The donated blood does not alter the recipients system in the long term.The blood cells each have a lifespan approaching 90-100 days after release, then they are broken down in the body and recycled.

If I am a beta thalassemia carrier female is it safe to have kids with a G6PD male?

If I am a beta thalassemia carrier female is it safe to have kids with a G6PD male?

Avoid 2 bad genes: One way to avoid having a child who inherited a bad trait, is to make sure that NOT both parents carry genes for that bad trait. So, a woman carrying a thalassemia gene (beta mutations are on chromosome 16, or alpha on 11) wants to marry a man with NO thalassemia mutations. Likewise, a man with G6PD (on chromosome X) wants to marry a woman with no G6PD. A doctor can check both the man and woman. ...Read more
