Genetic tests have greatly enhanced our understanding of complex human diseases. however, there are still some limitations. select the caveats of current genetic tests when analyzing common complex human diseases

Genetic testing refers to a kind of examination that determines the unusualities in chromosomes and genes. This is beneficial in correcting the probable genetic disorders that take place as a consequence of unusual genes.  

The genetic tests can determine ailments that possess genetic factors, but not environmental factors. Any test assists in the determination of a specific disorder but does not incorporate criteria of prevention and cure. The symptoms can differ from an individual to individual, the genetic tests can only help in finding the most usual traits.  

The correct answers are as follows: 1. Genetic tests can not account for potential environmental effects. 2. Genetic tests provide only a diagnosis not a cure. 3. The tests can only identify most common variants.

explanation:

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
