Question

multiple choice question
what is genetic drift?
transfer of genes from one species to another
random changes in the allele frequencies of a population over time
migration of individuals from one population to another
shuffling of exons of different genes to create new genes with novel functions

Explanation:

Genetic drift is defined as the random fluctuations in allele frequencies in a population over successive generations, often due to chance events like the survival or death of a small number of individuals. The other options describe gene - transfer between species (horizontal gene transfer), migration (gene flow), and exon - shuffling for new gene creation, which are different from genetic drift.

Answer:

Random changes in the allele frequencies of a population over time
