A study was conducted to investigate the levels of calcium and growth hormone excreted in chicken dung on a major chicken farm. The variances (V) were calculated and are shown below. $$\begin{array} { c c | c | }
\hline \text { Variance } & \text { Calcium } & \text { Growth hormone } \
\hline V _ { \mathrm { p } } & 321.2 & 95.8 \
\hline V _ { \mathrm { E } } & 119.7 & 69.4 \
\hline V _ { \mathrm { A } } & 107.4 & 10.1 \
\hline V _ { \mathrm { D } } & 94.1 & 16.3 \
\hline
\end{array}$$ a. Calculate the narrow-sense heritability for both traits (calcium and growth hormone levels).
b. Which trait, if any, will more likely respond to artificial selection?
