Greetings Doctor, I am marrying my cousin and both of us having same blood group (+B) is there any issue with that or not? As I have practically seen few couples who were cousins and their child born being abnormal ,defects or disabilities! Hopefully waiting for your reply sooner Regards.

Having same blood group is not a issue. But there are certain genetic diseases which can manifest in the children if born out of consanguineous marriage (i.e. In relation). Which we can have a thorough discussion.

Hi lybrate-user your dout is correct it could be happening when they married in familers. But it is not compulsory. It means there are more chance to be. But don't worry. Say to other it is better to avoid (if possible) do not marry with blood relations. Thanks.

B positive is a common blood group and as such will not cause any problems for a couple. If you are marrying your cousin, what you should do is get testing done for thalasemia or haemophilia. Also get full information about any other genetically linked diseases which run in the family.
