One advantage of genetic engineering over selective breeding is what?

(a.) selective breeding guarantees better results.

(b.) genetic engineering can produce large quantities of what we need quickly.

(c.) there are never any bad results with genetic engineering.

(d.) selective breeding only takes one generation to see the desired trait.

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.

silt loam

hope this

japan is the correct anwser because i already took the test and i passed it
