In most mammalian tissues, ubiquinone (also called coenzyme Q) has 10 isoprene units.

Dolichols of animals have 17 to 21 isoprene units (85 to 105 carbon atoms), bacterial dolichols have 11, and those of plants and fungi have 14 to 24.

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.

Amount of change in allelic frequency due to migration

m= proportional of migratory individual in  recipient population

qI – frequency of allele in source population

Adaptation is a characteristic that enhances the survival or reproduction of organisms .

Adaptations have evolved by natural selection, which is the centerpiece of On the Origin of Species
