Genetic drift is a process in which allele frequencies within a population change by chance alone as a result of sampling error from generation to generation. Genetic drift is a random process that can lead to large changes in populations over a short period of time.
Streptococcus pyrogenes : Round (or) Ovoid
Paenibaccilus polymyxa:
Aquaspirillum bengal: Helical
Explanation:
- Streptococcus pyogenes are gram positive, Round shaped, Anaerobic growth bacteria, Non-motile bacteria.
- Aquaspirillum bengal is helical in shape with its composition of deoxyribonucleic acid and cytosine. It is Gram negative and chemo-organotrophic. It is also motile with the help of flagella.
- Paenibacillus polymyxa is also known as Bacillus polymyxa which is capable of fixing nitrogen. It is found in soil, plant tissues and marine sediments. It has a major role in forest ecosystems and potential future applications as a biofertilizer and biocontrol agent in agriculture.
