The sex-ratio suppressing function of Nmy requires a pair of inverted repeats of bp [ 51 ]. Montchamp-Moreau C. The most pressing need, therefore, is for studies that will discover the functions of the individual genes associated with these patterns: de novo or transposed genes, or loci involved in hybrid sterility.

True JR, et al. This asymmetric pattern of X-linked introgression is generally consistent with the architecture of HMS between these populations i. Hybrid sterility is confined to the heterogametic sex due to the largely independent genetic control of meiosis and gametogenesis in the two sexes.

Suicide combinations of SD genes.

  • Spinach Spinacia olracea L.
  • Heteromorphic sex chromosomes, where one sex has two different types of sex chromosomes, face very different evolutionary consequences than do autosomes. Two important features of sex chromosomes arise from being present in only one copy in one of the sexes: dosage compensation and the meiotic silencing of sex chromosomes.
  • Fisher held strong views on race.

Population symbols are as in Fig. Figure 2. Sex chromosomes and speciation. Much of the evidence we present consists of detailed molecular and genetic studies of gametogenesis in pure species and interspecific hybrids, which by necessity are restricted to a few intensively studied model organisms.
