What is the p value from this test? (Pick the most accurate 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:
A) p> 0.5
B) 0.1
D) p< 0.05
E) p< 0.01

Autopolyploidy is a mechanism of speciation in plants, while allopolyploidy is a mechanism of speciation in animals. D. Autopolyploidy is sympatric, while allopolyploidy is allopatric.
