The ways in which a population is sampled to evaluate health or genetic diversity is influenced by its: distribution pattern birth rate death rate growth pattern

Option A, distribution Pattern

Explanation:

Distribution pattern or dispersal ability is a specific trait of population that determines the extent of possible movement and migration of a certain group from one habitat to other thereby standing at having a better chance of finding mates and maintaining genetic diversity. Therefore, in case if one fragmented population gets lost, there is scope of migrant population replacing it  

Hence, option A is correct

meiosis is the first to occur after the nuclei of opposite of opposite mating types fuse
