$8.$ Selective breeding can be conducted to alter the abdomen length in a species of fruit flies. Let$$s suppose you want to practice selective breeding to make longer flies. In a starting population, the average abdomen length is $1\mathrm{.}01$ mm$.$ You choose $10$ parents $($five males and five females$)$ with the following abdomen lengths: $0\mathrm{.}97,0\mathrm{.}99,1\mathrm{.}05,1\mathrm{.}06,1\mathrm{.}03,1\mathrm{.}21,1\mathrm{.}22,1\mathrm{.}17,1\mathrm{.}19,$ and $1\mathrm{.}20.$ You mate them and then analyze the abdomen lengths of $30$ offspring $($half male and half female$)$: $0\mathrm{.}99,1\mathrm{.}15,1\mathrm{.}20,1\mathrm{.}33,1\mathrm{.}07,1\mathrm{.}11,1\mathrm{.}21,0\mathrm{.}94,1\mathrm{.}07,1\mathrm{.}11,1\mathrm{.}20,1\mathrm{.}01,1\mathrm{.}02,1\mathrm{.}05,1\mathrm{.}21,1\mathrm{.}22,1\mathrm{.}03,0\mathrm{.}99,1\mathrm{.}20,1\mathrm{.}10,0\mathrm{.}91,0\mathrm{.}94,1\mathrm{.}13,1\mathrm{.}14,1\mathrm{.}20,0\mathrm{.}89,1\mathrm{.}10,1\mathrm{.}04,1\mathrm{.}01,1\mathrm{.}26.$ Calculate the realized heritability of abdomen length in this group of flies.
