Determine the proportion of offspring phenotypes that would result when two merle dogs mate, if one dog is true-breeding for the long-coat trait and the other dog is true-breeding for the short-coat trait. ResetHelp

100% long-coat

Explanation:

Assuming that the long-coat trait is represented by L allele and the short-coat trait by l allele.

True-breeding long-coat dog would have the genotype LL while true-breeding short-coat would have the genotype ll.

Assuming that the long-coat trait is dominant over the short-coat trait.

           LL    x    ll

        Ll   Ll   Ll   Ll

All the offspring would have Ll genotype and would appear with long-coat phenotypically. Hence, the proportion of offspring phenotypes is 100% long coat.

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.
