SUMMARY

Sam and Alex are first cousins who share a closer genetic relationship than Lee and Morgan, who are fraternal twins. This unique genetic connection arises because Sam and Alex's parents are identical twins, specifically Sam's mother's identical twin sister and Sam's father's identical twin brother. In contrast, Lee and Morgan, as fraternal twins, may have different fathers, which contributes to their lesser genetic similarity. The discussion highlights the complexities of genetic relationships and the implications of familial structures.

PREREQUISITES
  • Understanding of genetic relationships and terminology
  • Knowledge of the differences between identical and fraternal twins
  • Familiarity with the concept of incest and its genetic implications
  • Basic grasp of family tree structures and lineage
NEXT STEPS
  • Research the genetic implications of incestuous relationships
  • Learn about the genetic differences between identical and fraternal twins
  • Explore the concept of genetic relatedness and how it is measured
  • Investigate family tree analysis tools and techniques
USEFUL FOR

Geneticists, family counselors, and anyone interested in understanding complex familial relationships and genetic connections.

Sam and Alex are first cousins. Lee and Morgan are twins. But Sam and Alex are more closely related to each other than are Lee and Morgan, in terms of genetics. How did this happen?
Good luck! :-p

Allex' mother and father are, respectively, Sam's mother's identical twin sister and Sam's father's identical twin brother. The twins are fraternal twins, by definition could have different fathers.
 
Fraternal twins are Lee and Morgan. Sam and Alex resulted from incest where their father impregnated both of his twin sisters. Nevertheless, I'm assuming there is more than one answer to that riddle.
 
That wasn't the one I was thinking of, but it works!
 
It could happen without incest.
 
20questions, that's the answer I meant. :biggrin:
