please show work Nerodia sipedon insularum is a species of the Northern Water Snake that lives on islands in the western part of

Lake Erie. This snake exhibits polymorphism (many color forms) and can be described as Banded (BB), intermediate (Bb) and unbanded (bb). The mainland populations of this snake are all banded. The islands have sandy shores which the snakes reside compared to rocky shores of the mainland. In 1980-1984, Richard King conducted a study of mark recapture to look at the numbers of each of these morphs of snakes and for the Island of Pelee this was the population size: Banded: 71 individuals; Intermediate: 80 individuals; Unbanded 20 individuals. Give the genotypic frequencies for each morph and then give the allele frequencies for this population.

Answer:

Explanation:

From the question, the total population = 171 i.e (80+71+21)

Genetic frequency therefore; BB = 71/171 = 0.42

Bb = 80/171 = 0.47

bb = 20/171 = 0.12

Allele frequency therefore;

Allele B = 0.42+(0.50×0.47) = 0.66

Allele b = (0.50×0.47)+0.12 = 0.36

Note all values were rounded up to two significant figures

how could knowing that giraffes are four distinct species change the approach of conservationists or zookeepers who work with gi
muminat

Answer:

It would help the zookeeper in their breeding program so as not to interbreed the four different species, but rather to breed each species seperately, so as to keep the giraffe as a whole from population pollution by producing hybrids that do not have much conservation values.

Which has a greater impact on the survival of an organism, temperatures above its maximum temperature or temperatures below its
MAXImum [283]
A temperature above its maximum temperature tolerance it has the most impact over the organism survival. When under higher temperatures than the ones supported by the organism, the organism's proteins tend to denature and it becomes impossible to return to normal activity. While when under lower temperatures then the ones normally supported, the organism may stop its activity but can easily return to it once the temperature returns to ideal.
