Amalaria outbreak causing allele frequencies to change is an example of:

nonrandom mating.

the bottleneck effect.

genetic drift.

natural selection.

differential migration.

Answer: Natural selection.

Explanation:

The concept of natural selection was given by Charles Darwin.According to this concept, in a given environment the organisms that possess better adaptations have higher chances of survival and, leave behind a greater number of progenies.When malaria outbreak occurs, the allele frequencies change and only the organisms that possess the alleles which help them to survive this outbreak due to resistance against malarial infection will be selected by nature and hence, this is an example of natural selection.

Glucose, also called grape sugar, blood sugar or corn sugar, is among the simplest and one of the primary naturally occurring sugars. produced naturally by plants as the primary photosynthesis product, it is heavily used by living beings as a main energy source and is necessary for cellular respiration. chemically, it is a monosaccharide carbohydrate and serves as a building block for complex sugars like starch.
