Is dating a second cousin wrong
And the fact that close relatives are more likely to share them.Genes are Inherited from Your Parents Our DNA has the instructions to make us who we are.The other copy can pick up the slack so these “carriers” are usually fine.Each child of two carriers has a 25% chance of ending up with a disability.We have two copies of most every gene in our body and we inherit these genes from our parents.In fact, we actually get one copy of most of our genes from our mom and one copy from our dad.
This is why most of the time, carriers have perfectly healthy children! This is because they may have inherited the same gene change from their shared ancestors.
Some members of a family are more closely related than others.
For example, you share more of your genes with your brother and sister than you do with your uncle or aunt. First cousins only share about 12.5% of their genes and second cousins only 3.1%.
Our genes can tell us what color eyes to have, what color hair to have or even how tall to be.
They are a big part of what makes each of us unique!
