Figure 5.6 describes the results of X-chromosome inactivation in mammals. If fast and slow alleles of glucose-6-phosphate dehydrogenase (G-6-PD) exist in other species, what would be the expected results of gel electrophoresis for a heterozygous female of the following species?
A. Marsupial
B. Drosophila melanogastcr
C. Caenorhabditis elegans (We are considering the hermaph-rodite in C. elegans to be equivalent to a female.)
