This question asks us about the Hardy-Weinberg equilibrium.
While it may sound like a merger between a couple of boy sleuths and a Hollywood agent...
...the Hardy-Weinberg equilibrium is actually a really important principle in evolution.
It states that from one generation to the next, the genetic variation in a population
will remain constant....under a few conditions.
Here's a mnemonic that'll help us remember what the conditions are for a Hardy-Weinberg population.
Large Maggie Moo Really Sleeps.
It stands for...Large, Mutations, Migration, Random-mating, Selection.
L for Large: The population is infinitely large... so A is true. We can cross that one off.
M for: mutations are not occurring. Nope, not in our answer choices.
M for: migration is not occurring in or out of the population. That one looks like D....but
let's make sure...
R for: random mating occurs...meaning B is true...cross that one off.
And S for: natural selection isn't occurring. We can cross off C, too.
Since we've gone through the entire mnemonic, it looks like migration should NOT occur for
the conditions of Hardy-Weinberg equilibrium. This makes a lot of sense, because if the
organisms in a population kept migrating and mating in and out of the population...
...it'd be really hard to keep equilibrium of the genetic variation in a population.
D's our answer. This answer explanation is now over, but we're
