You are a wildlife biologist tasked with managing the endangered One-Eyed One-Horned Flying Only Purple People Eater left in the world are found in New York City and they have very low diver after. The only OEOHFPPEs left in the waterfall are pure IA!) people are still fair diverse at a locus that entirely controls their skin color- ersatz Fort pun pink polkaed purple, homozygous (A2A2 people eaters are pink and heterozygotes unit eaters, 10 pink eaters. I am purple with pink polka dots. You take a census of t (A1) people eaters are purple. of take a census of OEOHFPPES and find $10 purple people purple people eaters, cup, these two 180 polka-dotted people caters in Manhattan In Brooklyn you find 562 eat different oocysts between the purple Easters and 376 polka dotted people eaters. Easters generators, 362 polka doted, parole eaters. How much genetic difference exists between pink purple Should they be managed as a single population or as two different population?

Solution

The separation of gene pool of a population from the gene pool of other population due to mutation, genetic drift, and selection is termed as genetic divergence.

Genetic divergence in OEOHFPPEs

A1A1 homozygous people eaters are purple

A2A2 homozygous people eaters are pink

A1A2 heterozygous people eaters are purple with pink polka dots

According to Hardy Weinberg Equilibrium;

p + q = 1

In Manhattan,

A1A1 (p which is the frequency of purple people eaters) = 810/1000 = .81

A2A2 (q which is the frequency of pink people eaters) = 10/1000 = .01

A1A2 = 180

In Brooklyn,

A1A1 (p which is the frequency of purple people eaters) = 562/1000 = .56

A2A2 (q which is the frequency of pink people eaters) = 62/1000 = .062

A1A2 = 376

Observing the allele frequency, we can conclude that there is genetic divergence between the two groups and it will lead to two different populations due to allopatry.

Allopatry takes place in populations that are geographically separated.

Allopatric speciation is the most common form of speciation which occurs when population of a species become geographically isolated. When populations become separated there is no gene flow between them. Gradually the populations become genetically different in response to the natural selection imposed by their different environments.
