Duplications are repeated segments of genetic materials that result from unequal crossing over during meiosis or through a replication error prior to meiosis. They usually occur when homologous pairs do not line up correctly or in chromosomes with a lot of repeat sequences. Duplication of a segment of a chromosome would result in Genetic variability during evolution due to gene duplication.
<span>Transcript of A Cell is like a Factory. The cytoplasm contains the organelles, just likehow the factory floor contains all the machines and workers. The ER is where the ribosomes do there work to create proteins. ...

<span>the large population becomes smaller.
also, bottleneck is when a large population quickly shrinks. the effects of genetic drift becomes much stronger.
e.g: seals
alleles can be lost during bottleneck and the number of alleles left can shift dramatically in just a few generations.</span>
