John and his mother both have brachydactyly. John and his father both have Huntington disease. Both traits are rare and autosomal dominant. Johb's wife is phenotypically normal and is pregnant. Two-thirds of people who inherit the huntington allele show symptioms by age 50, and brachydactyly is 90% penetrant. Genotyping of the fetus reveals that the fetus has the huntington allele. What is the probability that the child will express both brachydactyly and Huntington disease by age 50 if two genes are 10 m. u. apart

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.
