Hint: Gene is a sequence of nucleotides in DNA that encodes for a specific characteristic or trait in an organism. A gene is known to be the fundamental unit of establishing hereditary. The study of genes and heredity is referred to as Genetics.
Step by step answer:An alternative forms of genes describing a single characteristic are known as alleles. Gene frequency is defined as the percentage of a population that consists of one type of allele at a particular locus. It is defined as the fraction of the population that carries one type of allele. It is expressed as a fraction of a percentage.
-Gene flow is described as the transfer of a genetic variation from one population to the other. If a variation in the gene is carried to a population where those gene variations do not exist, gene flow can thus trigger genetic variation.
-Genetic drift is a phenomenon in which gene frequency in a population changes over generations due to chance events. It happens in smaller populations and results in loss of alleles or a rise in the frequency of other alleles.
-Gene pool is the collection of all the alternative and allelic forms of genes within a population. It describes the population completely and tells us all the kinds of genes present and how these genes are distributed among the individuals of the population.
-Gene conservation is a method of conserving genes that have remained essentially unchanged throughout evolution that aims to understand the dynamics of genes in a population principally to avoid extinction.
Hence, the correct option is B. Genetic Drift
Note: The changes in gene frequency in a population is termed as microevolution. It encompasses changes due to various processes such as mutations in a gene, natural selection, gene flow, and genetic drift.
