Fourth cousins have one set of great-great-great-grandparents, but not the same great-great-grandparents. Double Cousins If two siblings in one family marry two siblings from another family and each couple has a child, the children are double first cousins.The word double in addition to the first cousin term is because because they share the same four grandparents.Removed cousin relationships is never measured by age, but only by generation differences.Twice removed means that there is a two-generation difference between cousins.If you are two generations younger than the first cousin of your grandparent, then the relationship between you and your grandparent's first cousin are first cousins, twice removed.Cousin relationships can be any combination of first, second, third and so on, with once removed, twice removed, and so on.Couples who are third or fourth cousins tend to have more kids and grandkids than other couples.And though considered somewhat of a cultural taboo, mating between "kissing cousins" makes good biological sense, say scientists.
Removed The relationships of cousins of different generations are explained by using the word "removed".The findings, which come from a recent study of Icelanders, shed light on how relatedness affects reproduction and ultimately the size of families.The researchers suggest marrying third and fourth cousins is so optimal for reproduction because they sort of have the "best of both worlds." While first-cousin couples could have inbreeding problems, couples who are far-removed from each other could have genetic incompatibilities.In that case, your father's first cousin is one generation younger than your grandparents and you are two generations younger than your grandparents.This one-generation difference is explained by saying that your are cousins "once removed.".
