In mendaliens, normal head top is dominant to bart head top, in which the top of the head is jagged. suppose a mendalien homozygous for normal head shape is crossed with one homozygous for bart head shape (see picture above). what are the genotypes of the two parents? what are the genotypes in the f1 generation? what are the phenotypes present in the f1 generation?

The genotypes of the two parents: normal head shape (HH) and Bart head shape (hh)

The genotypes in the F1 generation= Hh

The phenotypes present in the F1 generation= All normal head shape

Explanation:

Let's assume that the allele "H" is responsible for the normal head shape while the allele "h" gives Bart head shape. According to the given information, both the parents are homozygous. The genotype of the parent with normal head shape would be "HH" while that of the one with Bart head shape would be "hh". Since the normal head shape is dominant, all the F1 hybrid progeny would exhibit "normal head shape".

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.
