Study Notes
-
The more closely two individuals are related in a family, the more alleles they share in common.
-
The most closely related two individuals in a family are identical twins, who share the same alleles at every locus.
-
Siblings (including DZ twins) share 50% of their alleles with each other on average, but this is only on average.
-
The more distantly related two members of a family are, the fewer alleles they share in common.
