According to this model, Which of the following statements are correct?

#Unit 5. Developmental Biology
  1. SKN-1 is a maternal gene which activates GATA transcription factors in the EMS cell.
  2. The POP-1 signal prevents MED-1,2 proteins from activating the ectodermal transcription factors and instead activates the tbx-35 gene.
  3. The TBX-35 transcription factor activates mesodermal genes in the MS cell, including pha-4 in the muscles and hlh-1 in pharynx.
  4. TBX-35 also inhibits pal-1 gene expression, thereby do not inhibit the MS cell from acquiring the C- blastomere fates.

In Drosophila melanogaster, vestigial wings are determined by a recessive allele of a gene that is linked to a gene with a recessive allele that determines black body color. T. H. Morgan crossed black-bodied, normal-winged females and gray-bodied, vestigial-winged males. The F1 were all gray bodied, normal winged. The F1 females were crossed to homozygous recessive males to produce testcross progeny. Morgan calculated the map distance to be 17 map units. Which of the following information is correct about the testcross progeny?
