A dihybrid testcross is made to determine if genes C and D are linked.The results are shown in the table.
$\begin{array}{|l|c|r|}
\hline \text { Parent genotypes: } & C c D d \times c c d d & \
\hline & C c D d & 222 \
\hline & C c d d & 280 \
\hline \text { Progeny genotypes: } & c c D d & 280 \
\hline & c c d d & 218 \
\hline & & 1000 \
\hline
\end{array}$
-What is a reasonable conclusion based on the chi-square analysis?
A)There is a high probability that the deviation from the expected results is due chance.
B)One can say with a high degree of confidence that genes C and D are linked.
C)The analysis supports the null hypothesis.
D)Genes C and D are most likely unlinked.
