Answer:
The correct answer is letter D. Conventional breeding
Explanation:
In conventional genetic improvement a plant is crossed with another of the same species, with no incorporation of genes from another organism into the plant's genome, requiring repeated crossings until reaching the desired improved cultivar. Only in transgenics or genetic engineering are genes from another organism incorporated into the plant's genome.
A mutation is a new element added to the genetic buildup of an organism. this leads to new abilities that makes that organism adapt to different things, this is passed down through the organisms descendants which will help them get through situations other organisms can't, thus helping the entire species evolve.
