A Guam rail population has two alleles A1 and A2 at frequencies of 0.9 and 0.1, respectively. (a) what is the probability that A2 is lost in the next generation is 12 offspring are produced? (b) what is the probability that A2 is lost in the next generation if 100 offspring are produced?

Dr. sisko studies the flowering plant Mimulus cardinalis in an experimental population of size 1000 that grows in acidic soil. The color of the flower in this plant is determined by a single locus with two co-dominant alleles A1 and A2. Laboratory observations show that seeds from red and pink flower plants survive with equal success in the acidic soil but seeds from plants with white flowers (A2A2) have decreased fitness with a selection coefficient of s=0.2
| Phenotype | Red (A1A1) | Pink (A1A2) | White (A2A2) |
| # plants (adults) | 200 | 300 | 500 |
| Fitness | 1.0 | 1.0 | 1-s |
1) Calculate the allele frequencies in the next generation before selection.
2) Calculate the allele frequencies in the next generation after selection.
3) Calculate the genotype frequencies in the next generation after selection.
