Assume a single locus with two alleles, $\text{'}$T$\text{'}$ and $\text{'}$t$\text{'},$ that fitness$($s$)$ are defined as follows and all other assumptions behind Hardy$-$Weinberg equilibrium hold: Genotype TT Fitness $1\mathrm{.}01$

Tt $1$

tt $1\mathrm{.}005$

Derive an equation for change in p for this specific model of selection $($use s & t for the selection coefficients$).$
