A Diploid Plant Is a Trihybrid for Flower Color (Gene

question 32

Multiple Choice

A diploid plant is a trihybrid for flower color (gene "F") ,leaf size (gene "L") and seed weight (gene "S") ;its phenotype includes red flowers,large leaves,and heavy seeds.This plant is crossed to a tester plant (which has white flowers,small leaves,and light seeds) .The progeny is as follows:

$\begin{array}{|l|l|}\hline23 \text { Red, heavy, large } & 232 \text { White, heavy, large } \\\hline 25 \mathrm{Red}, \text { heavy, small } & 228 \text { White, heavy, small } \\\hline 230 \mathrm{Red} \text {, light, large } & 25 \text { White, light, large } \\\hline 235 \mathrm{Red} \text {, light, small } & 26 \text { White, light, small }\\\hline\end{array}$
What can be concluded about the linkage relationships of the three genes in question?

• A)Genes F,L,and S are linked.
• B)Genes F and L are linked,while S assorts independently.
• C)Genes F and S are linked,while L assorts independently.
• D)Genes S and L are linked,while F assorts independently.
• E)Genes F,L,and S are unlinked and assort independently.
