Which of the following is important for speciation
The correct option is (C) : Behavioural isolation
The prohibition of interbreeding between populations of a species that are present in various habitats is known as reproductive isolation. It preserves the traits of the species while also contributing to speciation, the creation of new species. Therefore, "Reproductive isolation" is the right response.
Given below are two statements:
Statement I: Transfer RNAs and ribosomal RNA do not interact with mRNA.
Statement II: RNA interference (RNAi) takes place in all eukaryotic organisms as a method of cellular defence.
In the light of the above statements, choose the most appropriate answer from the options given below:
Evolution is a process that occurs in changes in the genetic content of a population over time. Evolutionary change is generally classified into two: microevolution and macroevolution. The process of changes in allele frequencies in a population over time is a microevolutionary process. Three main mechanisms that cause allele frequency change are natural selection, genetic drift, and gene flow. On the other hand, macroevolution refers to change at or above the level of the species.
