Cats have recently migrated from Malaysia to an uninhibited island in the South China Sea. The gene pool of the migrants includes both alleles for straight (T) and stub (t) tails. You study selection pressures on these cats in the wild, finding the following survivorship in a cohort of 650 kittens.

1) Calculate survivorship and relative fitness for each genotype

2) Calculate the selection coefficient (s) and degree of dominance (h)
