Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

How is artificial selection different from genetic engineering?

A	Artificial selection is not related to genetics.
B	Artificial selection is not an example of biotechnology.
C	Artificial selection does not directly change a single organism’s DNA.
D	Artificial selection is used to make genetically identical copies of an organisms, cell, or piece of genetic material.

Explanation:

Detailed explanation-1: -The key difference between artificial selection and genetic engineering is that artificial selection selects already existing traits by breeding individuals that have desirable traits while genetic engineering modifies the genetic composition of plants or animals by introducing genes of new traits or silencing genes.

Detailed explanation-2: -Artificial selection does not directly change a single organism’s DNA. Artificial selection is used to make genetically identical copies of an organisms, cell, or piece of genetic material. Q. The main goal of biotechnology is to use living organisms and biological processes to improve life on Earth.

Detailed explanation-3: -Artificial selection selects for traits already present in a species, whereas genetic engineering creates new traits. In artificial selection, scientists breed only individuals that have desirable traits.
