In what way are mrf4, myoD, and the other muscle-inducing genes similar to the homeotic genes of Drosophila?

#Unit 5. Developmental Biology

mrf4, myoD, and the others encode homeobox- containing proteins.
mrf4, myoD, and the others encode "master-switch" transcription factors, which initiate a cascade of gene expression that leads to the differentiation of cells.
mrf4, myoD, and the others act as homeotic genes in Drosophila
mrf4, myoD, and the others are expressed exclusively in muscle, as are the homeotic genes of Drosophila.
