Question

The following figure shows four hypothetical relationships between the frequency of an allele in one generation p and its change in the next generation Ap-p-p) Imagine a population with an allele frequency of p 0.5. In the following generation the allele frequency changes to p 0.46. Which of the scenarios shown in the figure is consistent with these observations. Assume that genetic drift has no effect. 0002 0A 0.5 08 1.0 0.00.20.4 0 0.8 1.0 00 02 04 0 08 1000 02 04 08 8 10

Answer 1

1. C, since only graph c has only shown the value $\Delta$ P -0.04 (0.46-0.5),

so this is the only graph which shows the given observation.

2.in b and d, it will be eliminated

as in graph b and d, value of $\Delta$ P is decreasing in next generation
