Gallardo and Araneda (1994) studied populations of the rodent, Ctenomys maulinus, before and after an eruption of a volcano in t

he Andes. Survival was random, and the rodent populations after the eruption were only a small fraction of the size of populations before the eruption. Which of the following is likely to be TRUE of the surviving populations relative to the populations before the eruption?
a) Remaining populations will have reduced genetic diversity
b) Adaptive alleles have decreased in frequency
c) All of the answer choices are possible outcomes in this scenario.
d) Maladaptive alleles have increased in frequency

Answer:

A) Remaining populations will have reduced genetic diversity

Explanation:

A random mating population allows for genetic diversity as each individual have equal chance of been mated to and it allows for perpetuation of frequently occurring genes.

For a small population the frequency of allele is mostly fix with virtually all loci having the same genotype because mating is within small individual and genes whose frequency is few will be drifted out of the population.

Hence, after the eruption due to a small random population diversity will be reduced as diversity occur more in a large random mating population.

What are the phases of mitosis and meiosis and what do they do?
ehidna [41]
Prophase
Metaphase
Anaphase
Telophase

Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells. The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II. Meiosis I like mitosis is the cell division that produces diploid cells<span>. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number. </span>

I believe the answer would be A, because if water didn’t exist, there would be no presence of living things on earth. Water is a resource for life, thus, presence of living things.
