In pigs, the allele for a wavy, rough coat (r) is dominant to the allele for a soft, fine coat (r). a rough coat boar and a soft coat sow mate. they produce several litters, 50% are rough coat and 50% are smooth coat. what were the genotypes of the parents?

The genotypes of the parents are Rr and rr. The possible genotypes (and their phenotypes) are: RR (rough coat), Rr (rough coat), and rr (smooth coat). In a cross of rough coat boar (RR or Rr) and a soft coat sow (rr), there are half of the offspring with the smooth coat. We know that sow must be rr, but the boar can be RR and Rr. If it was RR, all of the offspring would be Rr and would have the rough coat. So, the boar has genotype RR.

well, you see. the answer to your question is quite simple. the thing that is big, powerful, and over 9,000 is your mom.

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.
