Answer:
P generation
Explanation:
The first two individuals that mate in a genetic cross is called the Parental generation or P generation. This is one of the terms used by Gregor Mendel, the father of modern genetics. P generation refers to the passing of genes or traits of the first set of parents crossed to the offspring. Their offspring are called the first filial generation or F1 Generation.
The correct answer would be D.
After many generations, only those with genes suitable to live in harsh environments can live. These genes are passed onto their offspring and then we see a rise in antibiotic resistant strains of bacteria such as Methicillin Resistant Staphylococcus Aureus (MRSA).
There would be dead animals overloading the Earth. Think about it, without worms and other things that break down dead things they would still be here and just sit there.
It would happen that the effectiveness of an original vaccine could become less if there was a mutation in the virus that caused the protein spike to change because the antibodies created would not be specific for the new virus.
<h3>What would happen to the mutated virus?</h3>
Vaccines trigger an immune response to fight disease-causing organisms, a mutation in the virus to be fought would change the effectiveness of this immune response, as the specificity would not be the same with the mutant virus.
With this information, we can conclude that The immune response would not be specific for the new virus that caused the protein spike to change.
