zmey [24]

I would think that the firearm should be passed over the fence and not carried in the hands if it is a rifle to avoid it accidentally going off and make sure that it is not loaded or with no shells in the chamber for safety because it could conceivably fire if the bearer fell while crossing the fence.

What is the biological significance of genetic diversity between populations? What is the biological significance of genetic div

mrs_skeptik [129]

Explanation:

A) Genes for traits conferring an advantage to local conditions make microevolution possible.

For example, Galapagos finches show variation in beak sizes and shapes related to their niches and available food source; the finches developed adaptations to their environment. Their specialized beaks allow them to adequately exploit the available resources, by utilizing the more abundant food source.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells. This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained.

Conversely in meiosis, the number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell. Crossing over, independent assortment, and random fertilization ensure genetic variation.

This variation refers to the genetic characteristics present within a species; they form new traits called alleles, which may confer adaptations that increase the fitness of a species, along with ensuring survival by conferring an advantage.

Additionally, natural selection, mutation, genetic drift and gene flow lead to microevolution; over time, this is seen as changes to allelic frequencies within a population
