Genes a, b, and c are located on the same chromosome. testcrosses show that the recombination frequency between a and b is 28% and that between a and c is 12%. can you determine the linear order of these genes? ð•xplain.

Genes that have a higher recombination frequency tend to located closer to each other than genes of lower recombination frequency. This is because genes closer together have a higher probability of being on the same chromosome after crossing over or homologous recombination during meiosis. Hence as AB have a higher recombination frequency they are located closer to each other than AC. Thus the order can be ACB or CAB. If the recombination frequency between C and B is high as well, the answer would be ACB, otherwise, it would be CAB.

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.
