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
The zonation of flora and fauna along an altitudinal transect similar to that found along latitudinal transects is an expression of the the life zone concept.
<h3>What is life zone concept?</h3>
- C. Hart Merriam created the term "life zone" in 1889 to refer to regions with comparable plant and animal groups. Depending on height, location, and latitude, the climate and ecology of many places on the planet naturally divide into life zones.
- Altitudinal zonation is the term for the generally substantial dependence on elevation: the average temperature of an area falls as the height increases.
- The US has thirty-eight life zones, including one boreal, twelve cool temperate, twenty warm temperate, four subtropical, and one tropical (34% of the world's life zones and 85% of the temperate ones).
