In one plant species petal color follows INCOMPLETE DOMINANCE. If there are alleles for both red and white plants, what would a heterozygous plant's
phenotype be?
Red
Pink
White
Red and White

Pink

Explanation:

Incomplete dominance is when one allele is not entirely dominant over the other. The resulting phenotype of the heterozygote is intermediate between the two alleles. That means the flowers would be pink.

Red  - no, this would be true if red was dominant to white

Pink  - yes, this is an intermediate phenotype

White  - no, this would be true if white was dominant over red.

Red and White  - no, this would be true if the alleles were co-dominant and both equally but independently expressed.

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.  

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
