1. The R locus determines flower color in one species of plant. The geno­type RR gives red flowers, the genotype Rr pink flowers, and the genotype rr white flow­ers. The frequencies of genotypes RR, Rr, and rr in a population of plants are 0.4, 0.4, and 0.2, respectively. This population produces a new generation of ex­actly 200. Pre­dict the numbers of plants with red, pink, and white flowers in this genera­tion.

QON\# find \( T(t) \) and \( N(t) \) if \( N(t)=\left(t^{2}-1\right) \hat{i}+t j ; t=1 \) Solution:- \[ \begin{array}{l} R^{\prime}(t)=2 t \hat{i}+\hat{j} \\ \left|\alpha^{\prime}(t)\right|=\sqrt{(2 t)^{2}+(1)^{2}} \\ \left|\alpha^{\prime}(t)\right|=\sqrt{4 t^{2}+1} \\ T(t)=\frac{2 t}{\sqrt{4 t^{2}+1}} \hat{i}+\frac{1}{\sqrt{4 t^{2}+1}} \hat{j} \end{array} \] Put \( t=1 \) into eq(1) \[ T(1)=\frac{2}{\sqrt{5}} \hat{i}+\frac{1}{\sqrt{5}} \hat{j} \] Taking derivative of eq(1) \[ \begin{array}{l} \frac{d}{d t} T(t)=\frac{d}{d t}\left(\frac{2 t}{\sqrt{4 t^{2}+1}} \hat{i}+\frac{1}{\sqrt{4 t^{2}+1}} \hat{j}\right) \\ T^{\prime}(t)=\frac{\sqrt{4 t^{2}+1}(2)-(2 t)\left(\frac{4 t}{\sqrt{4 t^{2}+1}}\right)}{\left(\sqrt{4 t^{2}+1}\right)^{2}} \hat{i}- \\ d / d x\left(\sqrt{4 t^{2}+1}\right)=\left(4 t^{2}+1\right)^{1 / 2}=\frac{1}{2}\left(4 t^{2}+1\right)^{-1 / 2 d}\left(4 t^{2}+1\right) \\ =\frac{1}{2}\left(4 t^{2}+1\right)^{-1 / 2}(8 t)=\frac{4 t^{4}}{\sqrt{4 t^{2}+1}} \end{array} \]
