And we can look in particular at three types of siblings: identical twins, twins that actually share 100 percent of their genetic information and shared the same intrauterine environment, versus fraternal twins, twins that actually share 50 percent of their genetic information, versus regular siblings, brother-sister, sister-sister, also sharing 50 percent of their genetic information, yet not sharing the same intrauterine environment.
Dhe mund te shohim vecmas tre lloj lidhjesh: binjake identike, binjake qe ndajne 100% te informacionit te tyre gjenetik dhe qe kane ndare te njejtin ambient brendauterin, kundrejt binjakeve heterozigot, binjake qe ndajne vetem 50% te informacionit te tyre gjenetik, kundrejt vellezerve/motrave normale, vella-moter, moter-moter, qe gjithashtu ndajne 50% te informacionit te tyre gjenetik, nderkohe nuk kane ndare te njejtin  ambient brendauterin.
