Question 17

Multiple Choice

In Drosophila, singed bristles (sn) and carnation eyes (car) are both caused by recessive X-linked alleles.The wild-type alleles (sn⁺ and car⁺) are responsible for straight bristles and red eyes, respectively.A sn car female is mated to a sn⁺ car⁺ male and the F₁ progeny are interbred.The F₂ are distributed as follows:
$\begin{array} { | l | r | } \hline s n~ c a r & 55 \\\hline s n~ c a r^+ & 45\\\hline s n ^{+ c a r} & 45 \\\hline s n ^ { + c a r +} & \underline{55} \\\hline & 200 \\\hline\end{array}$ $In Drosophila, singed bristles (sn) and carnation eyes (car) are both caused by recessive X-linked alleles.The wild-type alleles (sn+ and car+) are responsible for straight bristles and red eyes, respectively.A sn car female is mated to a sn+ car+ male and the F1 progeny are interbred.The F2 are distributed as follows: \begin{array} { | l | r | } \hline s n~ c a r & 55 \\ \hline s n~ c a r^+ & 45\\ \hline s n ^{+ c a r} & 45 \\ \hline s n ^ { + c a r +} & \underline{55} \\ \hline & 200 \\ \hline \end{array} -If you want to analyze this data for evidence of linkage between sn and car, what is the null hypothesis?
