Who am i closest to in genetic terms?

Question

I have a half-sister (same mother not the same father)...am i more related to her or my female cousin? my cousins mum and my mum are sisters....so our mums share the same blood... the only difference between me and my cousin is our fathers...and the only difference between me and my sister is our fathers?? very confusing i know.

Answer 1

You share fifty percent of the genes of one parent and twenty five percent of the genes of one full sibling, so with a half sibling you share 12.5 percent.

Your mom and her sister share 25 percent of their genes. Her sister's daughter has half of her mother's genes, therefore you and your cousin also share 12.5 percent of the same genes.

Edit: Ok I made a mistake. Your mother's niece shares 12.5 of your mother's genes. So you and your cousin only share 6.25 percent of the same genes. You are more closely related to your half sister and your half brother.

Answer 2

You're more related to your half sibling, because you share a parent. You and your cousin only share a grandparent.

Answer 3

Your Half Sister.

Your mom links you and your sister.

Your Grandparents link you and your cousin.
