    Description: Balancer chromosomes are multiply inverted and rearranged chromosomes used in Drosophila melanogaster for many tasks, such as maintaining mutant alleles in stock and complex stock construction. Balancers were created before molecular characterization of their breakpoints was possible, so the precise locations of many of these breakpoints are unknown. Here, we report or confirm the positions of the 14 euchromatic breakpoints on the 2 nd chromosome balancers SM1 , SM5 , CyO , and SM6a . This total includes three breakpoints involved in a complex rearrangement on SM5 that is associated with the duplication of two genomic regions. Unbiased sequencing of several balancers allowed us to identify stocks with incorrectly identified balancers as well as single and double crossover events that had occurred between 2 nd chromosome balancers and their homologs. The confirmed crossover events that we recovered were at least 2 Mb from the closest inversion breakpoint, consistent with observations from other balancer chromosomes. Balancer chromosomes differ from one another both by large tracts of sequence diversity generated by recombination and by small differences, such as single nucleotide polymorphisms (SNPs). Therefore, we also report loss-of-function mutations carried by these chromosomes and unique SNP and InDel polymorphisms present on only single balancers. These findings provide valuable information about the structure of commonly used 2 nd chromosome balancers and extend recent work examining the structure of X and 3 rd chromosome balancers. Finally, these observations provide new insights into how the sequences of individual balancers have diverged over time.

    Notes: The paper discusses the effect of a weak layer in the upper mantle on the deformation of the crust arising from atmospheric loading, and on the isostatic compensation process. It also points out that S phases with periods of I second are much more strongly damped than S phases with periods of 10 seconds or more, and than P phases with short periods. The damping arising from a liquid layer is proportional to the square root of the frequency and does not provide a satisfactory explanation. Scattering of the kind suggested by Jeffreys, or any other mechanism leading to the firmoviscous law, gives rise to damping proportional to the square of the frequency and is sufficiently frequency sensitive to be consistent with the observations. The differences between P and S can only be accounted for in terms of different behaviour of the elastic constants for dilatational and distortional movements.

    Notes: Analysis of the Early Rise traveltimes in the United States shows that on several of the profiles there are features which can be interpreted as indicating a low-velocity zone above 200 km, i.e. that the continental lithosphere thickness is less than 200 km. The explosion data from the Nevada Test Site, GNOME and Early Rise are all consistent with Lehmann's suggestion that there is a discontinuity at a depth of about 200 km. Comparison of the observed data between 15° and 23° with model calculations shows that the major differences between the western and central-eastern United States upper mantles occur above 200 km. It appears that the only reasonable explanation for the 200 km discontinuity is that it represents the termination of a zone of partial melting.

    Notes: In an earlier paper it was suggested that it was failure in the region between 250 and 600 km below the surface which determined the periodicity of orogenic phenomena. In this paper estimates of the cross-sectional areas of the oceanic troughs and of the mass deficiencies reflected in the strips of large negative gravity anomalies are given and it is inferred that the interval between successive periods of failure is 50 million years.It is pointed out that if the troughs are formed in the manner described in the earlier paper then a regression of sea-level of about 70 metres will occur as a result of their formation. Finally some aspects of the development of the trough regions into mountain ranges are discussed qualitatively.
