Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
It has been found that the tenderness of beef can be predicted by analyzing a cow’s genes. So, commercial tests are now available for farmers to be able to determine which of their cows possess the “tough” gene and which possess the “tender” gene. If a farmer routinely tests his cattle and only allows cows with the “tender” gene to mate, what is he doing?
A
Forensic testing
B
Selective breeding
C
Genetic bias
D
Recombinant DNA technology
Explanation: 

Detailed explanation-1: -What have scientists found to be the most efficient and effective way to insert new sequences into an individual? Scientists use viruses to insert specific gene sequences. The Human Genome Project began in October 1990 and was completed in 2003. What was the major goal of the Human Genome Project?

Detailed explanation-2: -Genetic engineering, also called recombinant DNA technology, involves the group of techniques used to cut up and join together genetic material, especially DNA from different biological species, and to introduce the resulting hybrid DNA into an organism in order to form new combinations of heritable genetic material.

Detailed explanation-3: -Crops that have been genetically engineered to resist disease would increase the use of pesticides. Animals that consume genetically-engineered crops will no longer be able to reproduce. Human DNA might experience recombinant mutations with the plant DNA.

Detailed explanation-4: -The genetic engineering process The gene for human insulin is inserted into the gap in the plasmid. This plasmid is now genetically modified. The genetically modified plasmid is introduced into a new bacteria or yeast cell. This cell then divides rapidly and starts making insulin.
