The concept that some individuals within a species have a hereditary advantage over their competitors that enables them to produce more offspring is called

Is called natural selection.

Explanation:

According to natural selection, differences in the phenotype of individuals of the same species make some of them have prevalence over the others and thus reproduce more easily.

The phenotype is the set of observable characteristics of an individual. For example, if some individuals from some animal species are taller and thus able to reach food that their pairs can´t, they will survive when food scarce, then they will reproduce and their offsping will have that ability.

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.
