Effects on kids whose parents having blood b+?!
Question:
Effects on kids whose parents having blood b+?
side effects on children having parents same blood type,
Answers:
There's no side effect from parents having the same blood type. An incompatibility can happen from parents having different blood types that give a child the positive Rh type from the father while the mother has the negative Rh type. That's usually OK for one pregnancy, but then the mixing of maternal and fetal blood at delivery immunizes the mother against the Rh+, making another pregnancy with an Rh+ baby difficult.
Type B is either homozygous BB or heterozygous BO, so children can differ from their parents. A child of two type B's can be type O. There's no side effect to that, though, to my knowledge.
The reason it's a bad idea for siblings to have children together are genes that are deadly as homozygotes, like cystic fibrosis. Then it's bad for a couple to both have the same genes. That doesn't apply to blood types.
