Fig. 2. Pph13^hazy genetic interval and homeodomain protein comparisons. (A) Recombination and deficiency mapping placed Pph13^hazy in a small genetic interval 21C7-21D1 on the left arm of the second chromosome. All deficiency and duplication stocks were obtained from the Bloomington Stock Center, except Df(2L)4989, which represents an X-ray induced allele of Pph13^hazy (A.C.Z., unpublished). (B) Comparison of the Pph13 homeodomain to Drosophila Aristaless (Al) and Aristaless-related homeobox protein (Arx). The red asterisk represents the amino acid change in Pph13 (W to Stop).
