So, how could these 2 guys be blood brothers (same mother and father) yet look completey different
The guy on the right is my buddy. Both these guys are blood brothers. The guy on the right is the oldest and the massive alpha male looking guy is 5 years younger. So, like what happen? How could they look so different but be so closely related?
They are Turkish. The red mark are their sisters, but i blurred them out.
@GanglandCriminal97 Yes, and no. Unless they are identical twins, then it's a yes.
Every human has 46 chromosomes. 23 pairs. They get one set of 23 from mom and one set from dad. So each parent has 46, but only gives 23 to the offspring. That means for each chromosome, the kids in the picture either got the chromosome grandpa gave to mom or the one grandma gave to mom, but not both. That randomness happens 23 times for mom and 23 times for dad. 46 times in all. The odds of two brothers getting matching genes isn't technically zero, but it's so small that functionally it is zero. The same for two brothers having no matching genes. The real results end up between those two. They share some genes but not all genes. The average should be about half. But that's just the average. Maybe these two are outliers and share only 40%.
Or maybe mom had something on the side. Who knows.
