Step 2: rna polymerase unwinds the double stranded dna and begins assembling rna nucleotides. Mutant condition is dominant, but can be bene cial. Mutant form causes expression in the thorax and also the head, causing legs to grow instead of. Purpose: (in animals) produce haploid gametes (half the parents" genetic material) At the end of meiosis i, the 2 cells are already haploid. Meiosis ii splits the 2 sister chromatids to 1 chromatid.
