The sex combs of Utx1/Utxf01321 males contain fewer teeth (6-8) than wild type (~10).
Homozygous wings are wrinkled, have venation defects, are down-curved, and have an irregular margin.
Utx1/Utxf01321 wings sometimes contain fluid-trapped blisters.
Utxf01321/Utx[+] is a suppressor of wing margin phenotype of Ser1
The wing notching phenotype of Ser1 or Df(1)N-8 heterozygotes is dominantly suppressed by Utxf01321.
