Can you marry your maternal cousin who are same blood group with you?

It is generally not advisable to marry a close relative, such as a maternal cousin, due to the increased risk of genetic disorders in offspring. When closely related individuals mate, the chances of inheriting two copies of the same rare genetic mutation increases, which can lead to genetic diseases or disorders. This risk is higher if both parents carry the same genetic variant.

However, it's important to note that having the same blood group does not directly indicate a genetic risk. Blood groups are determined by specific antigens on red blood cells, and sharing a blood group does not necessarily mean that individuals are closely related or at an increased risk of genetic disorders.

Before making any decisions regarding marriage, it is recommended to consult with genetic counselors or medical professionals who can assess your specific family history and provide personalized advice based on your unique circumstances. They can evaluate your genetic compatibility, discuss the potential risks, and help you make informed decisions about your reproductive choices.
