Complete question:
Phenotype               Genotype         Number of Individuals 
Long-tailed                     TT                               260
Long-tailed                      Tt                                160 
Short-tailed                      tt                                 80
If 20% of the long-tailed cats got their tails stuck in something and failed to reproduce, what would be the expected change in frequency of T in the next generation
Answer:
The expected change in allelic T frequencies probably changes from 0.6 to 0.57 in the following generation.
