What does the data analysis allow you to conclude about linkage between sn and car? (Select all that apply.)
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:
A) There is a high probability that the deviations from the expected number of F2 in each genotype class are due to chance.
B) The data do not allow rejection of the null hypothesis.
C) The p value is high meaning that the data is significant.
D) There is good evidence that cn and car are linked.
A) There is a high probability that the deviations from the expected number of F2 in each genotype class are due to chance.
B) The data do not allow rejection of the null hypothesis.
