The amount of change in q is directly proportional to the migration (m); The magnitude of change is also affected by the differences in allelic frequencies of the two populations (qI - qII); What is amount of change when 200 migratory individuals are merge in recipient population size of 1800. Allele frequency of q1 of source and recipient population is .80 and .20 respectively.

Following statements are regarding to the wingless gene in drosophila.

A. In the cells transcribing the wingless gene, wingless mRNA is translocated by its 3’UTR to the apex of the cell. At the apex, the wingless message is translated and secreted from the cell.

B. The cells expressing engrailed can bind this protein because they contain Patched, which is the Drosophila membrane receptor protein for Wingless.

C. Binding of Wingless to Frizzled activates the hedgehog signal transduction pathway, resulting in the continued expression of engrailed.

D. Wingless protein also acts in an autocrine fashion, maintaining its own expression.
