Cows are selectively bred to produce milk. Which of the following will cause the next generation to receive the trait to produce large quantities of milk?
A
nutrients in their food
B
mineral in their water
C
electrical impulses to their brains
D
information in their chromosomes
Explanation: 

Detailed explanation-1: -To form a fetus, an egg from the mother and sperm from the father come together. The egg and sperm each have one half of a set of chromosomes. The egg and sperm together give the baby the full set of chromosomes. So, half the baby’s DNA comes from the mother and half comes from the father.

Detailed explanation-2: -A: CRISPR genome editing allows scientists to quickly create cell and animal models, which researchers can use to accelerate research into diseases such as cancer and mental illness.

Detailed explanation-3: -Recombinant DNA technology is the joining together of DNA molecules from two different species. The recombined DNA molecule is inserted into a host organism to produce new genetic combinations that are of value to science, medicine, agriculture, and industry.

Detailed explanation-4: -Selective breeding makes use of existing, naturally present gene variants in a species? and the natural process of breeding. Genetic engineering involves a direct change to an organism’s genome in the laboratory. Gene variants made through genetic engineering can be passed from one generation to the next.
