If a Gene in Drosophila Is Expressed Only When an Imaginal

question 32

Multiple Choice

If a gene in Drosophila is expressed only when an imaginal disc (A) begins to differentiate, it is referred to as a homeotic gene. Recessive mutations in such genes often result in loss of function so that the structure does not develop. If the gene is expressed, but in a different imaginal disc (B) , what is the result?

• A)loss of function of disc B's primary gene
• B)gain of function of several inappropriate genes in disc A
• C)gain of function in disc B at the "wrong" location
• D)deregulation of gene expression throughout disc A
• E)deregulation of gene expression throughout disc B
