The overall effect of migration is twofold: 

1.it prevents populations from becoming genetically different from one another, 

2.it increases genetic variation within populations.

In selective autophagy

specific cargo is packaged into autophagosomes that tend to contain little cytosol, mediates the degradation of worn out, or unwanted, mitochondria, peroxisomes, ribosomes, and ER; used to destroy invading microbes.
