Errors sometimes occur when copies of dna are made during dna replication these errors are called mutations true orfalse

Errors do sometimes occurs mainly at the time of DNA replication. Mutations refers to the changes in the DNA sequence made at the time of DNA replication, however, the DNA replication procedure possesses characteristics that minimize mutations.

The three small scale mutations, which can take place at the time of DNA replication are nucleotide substiution, inversion and translocation. Hence, the given statement is true.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
