Problem:
In Drosophila melanogaster, the phenotype "curly wings" is due to a dominant allele Cy that is lethal when homozygous. A population is established with an initial frequency of Cy equal to 0.168.
Question: Calculate the expected frequency in the next generation, assuming:
- that the relative fitness of +/+ and Cy/+ are both 1.0
- that the relative fitness of +/+ is 1.0 and Cy/+ is 0.5
Show the pedigree and your calculation.
