1 answer:
melamori03 [73]3 years ago
3 0

Answer:

Several generations

Explanation:

For a completely new species to branch out of its predecessor, a series of germline mutations are needed. Each mutation is spontaneous , random, directionless and depends on individual and environmental factors. Only favourable mutations (purely on luck) pave the way to speciation.

Thus, speciation is not a single generation phenomenon. It takes several generations to fully manifest. The phenomenon of mutation being a random event makes speciation an ever longer procedure.

Commonly, genes from bacteria are inserted into a crop's chromosomes to produce pesticide substances to kill insects

For drought, I'm not fully sure, but Maize is a very drought resistant crop often introduced to communities which receive little rainfall. Maybe they take a gene from the maize crop and insert it into the chromosomes
