Consanguinous marria: We discourage consanguinous marriages because sometimes there are genes that when they meet a second one to make a pair ( i mean on e from father and one from mom), the babies might show severe genetic diseases although there are also very healthy kids from consanguinous marriages.

Possibly: We all carry an estimated 4 autosomal recessive genes to conditions that may involve metabolic or other problems like cystic fibrosis.Conditions that hide in the recessive state but can be deadly when two carriers produce an affected child. Cousins are so closely related that they likely carry some of the same recessive genes.If so, every offspring could have a genetic defect.
