What is true about the isolated small tribal populations?
1. There is a decline in population as boys marry girls only from their own tribe
2. Hereditary diseases like colour blindness do not spread in isolated populations
3. Wrestlers who develop strong body muscles in their lifetime pass this character
on to their progeny
4. There is no change in population size as they have a large gene pool
