<span>REM sleep is a period of sleep where your eyes move rapidly (Rapid Eye Movement). After a period of REM sleep, your body experiences 5 to 15 minute periods of non-REM sleep. During this lighter sleep it is much easier for you to be awakened. There are different periods of REM sleep which can last from 10 minutes to one hour. The longer you sleep, the longer the REM period will last. This cycle will occur on average every 90 minutes.</span>

<h3>What is genetic variation in population?</h3>

The presence of various alleles, or different gene versions, within a population indicates genetic variety.
If there is genetic variation, then everybody in the population will have various genotypes depending on the alleles they carry.
Genetic loci that have many alleles are said to be polymorphic. Human characteristics like blood type and eye color, for instance, are polymorphic.
