new species can form through allopatric or sympatric speciation. the mechanisms of genetic drift will act more strongly on populations that are initially separated in allopatry than on those initially separated in sympatry.
<h3>What is
genetic drift ?</h3>
In a population, genetic drift refers to a shift brought on by chance in the frequency of an already present gene variant. Gene variations could completely vanish due to genetic drift, which would limit genetic diversity. Furthermore, it may lead to the widespread spread and even fixation of previously rare alleles.
<h3>Why does it happen?</h3>
The term "genetic drift" refers to haphazard changes in the population's gene variation frequency. Genetic drift occurs throughout time when the frequency of different alleles, or variable forms of a gene, fluctuates randomly. Allele frequencies are changed to account for these variations in allele presence.

Photosynthesis and cellular respiration are<u> chemical reactions</u> that occur in cells.
<h3>What is photosynthesis and cellular respiration?</h3>
Photosynthesis is the process of making food through carbon dioxide, water and sunlight. It is an anabolic reaction.
Cellular respiration is the process of breaking down of food molecules by oxygen. It is a catabolic reaction.
Thus, the correct option is a, chemical reaction

<span>A clone representing myostatin would be found in the genomic library made from muscle approximately one time out of every sixty thousand. Under the given conditions, the human genome and average insert size, the frequency of that particular type of clone can be estimated to be very near the probability of 1/60,000. This can be expressed either in fraction form or in descriptive words and maintain the same level of meaning.</span>
