The thylacine is an extinct marsupial that once roamed tasmania and australia. there are several preserved specimens in existence. which of the following dna technologies offers the best chance for bringing back the thylacine?

hylacine, the last existing member of family Thylacinidae, was the largest known carnivorous marsupial of the modern era. This species went extinct in the twentieth century.

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.

explanation:

meteorologists would compare a new weather map with one 24 h old to see how fast a front is moving.
