Re: Marrying a cousin - 11.20pm BBC2 tonight
well their are health risks for your children. if you have a recessive genetic disease in your family but neither your cousin or yourself show that genetic disease you still can have a possibility of having the recessive allele and therfore have higher chances of getting children with that disease. that is why many purebreed animals have genetic deformitis or other genetic diseases. because all the imbreeding highers the chances of getting these problems. if you still have trouble understanding recessive and dominant alleles and other gene stuff read a bio book.
