Is dating a second cousin wrong
Like people who are not related, your actual risk depends on the genes you and your spouse have.If you are concerned about your risk for having a child with a disability, you should see a genetic counselor in your area.Because genes are passed down from person to person, everyone in a family shares some percentage of their genes with everyone else in their family.That is why you are linked to everybody in your family tree!Relatives Share Genes As I said above, genes are passed down to you from your parents.And your parents got their genes from their parents (your grandparents) and so on.
Even with improvements, as of 2006 the median age of survival for people with CF is 37.5 years.What this all means is that while there is increased risk, it doesn’t really qualify as a “high chance.” Even first cousins at 5% aren’t that big of a risk.Keep in mind though that these are average numbers.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!
That’s why you usually (but not always) look more like your brother or sister or parents than other people in your family. No matter how related two family members are, they all share some genes in common.
