Answer:
The correct answer will be option-A.
Explanation:
Genetic variation is the difference in the DNA sequences of individuals in a population. Genetic recombination is the main reason for the diversity of organism on earth.
The genetic variation takes place during gamete formation by recombination of DNA sequences which takes place during prophase of meiosis I.
Since genetic variation involves changes in the coding segments of the DNA called genes which leads to mutations, therefore, flowering time does not influence the genetic variation and option-A is the correct answer

<u>Answer:</u> Mutations are the most fundamental way to add new genes to a gene pool.
<u>Explanation:</u>
Mutation refers to the process through which the normal sequence of altered. It may be either acquired or hereditary. It leads to addition of new genes to a gene pool.
The reason for not considering other statements as true are:
1. It is the hereditary mutation that are passed form parent to offspring's and acquired mutation is caused by external factors.
2. Acquired mutation are caused by external factors such as radiation.
3. Germ line mutation are important to evolution because they can be inherited.
Coral provide the place for algae to grow on. Algae attract microorganisms for coral to feed from.
