The ant, Myrmecia pilosula, is found in Australia where it is called a "bulldog ant" because of its aggressive behavior. It is particularly interesting genetically because it has only one chromosome. It is diploid, and sex is determined by the number copies of this chromosome an individual has: females have two and males have one. The drawings below illustrate metaphase of meiosis or mitosis in this organism with alleles for a single gene indicated (T/t). Chromosomes are not to scale and spindles are not drawn in, however the relative positions of chromosomes are significant in these drawings. Choose a letter A, B or C to indicate which drawing could illustrate each cell division stage described on the left.
