Assuming that Creeper chickens have the same fitness as Normal chickens (probably not the case), construct a selection model for the Creeper gene. If you started a new chicken population (generation 0) with 100 Creeper chickens, what frequency of Creeper would you expect in the next generation (generation 1)? Calculate delta q (where q is the frequency of the Creeper allele) between generations 0 and generation 1. We derived the following equation for delta q with this selection model: (-spq^2)/(1-sq^2). Does the delta q you calculated agree with the delta q from this equation?
Genetics Question?
There are still a few assumptions that have not been met enough to answer this question:
Is the creeper gene recessive or dominant?
If it is recessive, then the generation 1 frequency would be one-hundred percent, because the only way to get a creeper chicken from recessive creeper genes is if each creeper chicken had both of that gene's DNA strands with the creeper recession.
If the creeper gene is dominant, then you could expect seventy-five percent of them to be creepers in gen1, because you would expect all of the gen0 chickens to be either double creeper or single creeper, which would make half double and half single, meaning that half of the gen1 offspring would be from the half of the single-creepers, making half of them normal.
So, without that info, you cannot proceed.
I guess you would have to ASSUME that the creeper gene is dominant for this whole scenario to make sense.
In that case, plug it it and do the math.
