Cell 17— HSP is required for desynapsis of synaptonemal complexes during meiotic prophase in juvenile and adult mouse spermatocytes. Interactions between Mei4, Rec, and other proteins required for meiotic DNA double-strand break formation in Saccharomyces cerevisiae.

Differential distribution and association of repeat DNA sequences in the lateral element of the synaptonemal complex in rat spermatocytes. These breaks are concentrated at 'hot spots' that are are genetically and epigenetically determined, and influence haplotype structure.

In vitro -differentiated embryonic stem cells give rise to male gametes that can generate offspring mice. Borts, R. The mammalian synaptonemal complex: a scaffold and beyond.

A common model of sex-chromosome evolution implies gradual cessation of recombination between the proto-sex chromosomes. The incipient alleles of the opposite mating type were then either gene converted onto the newly-formed bipolar chromosome or, more likely, were linked via dual recombination events Figure 7collapsing the tetrapolar system to a bipolar one via a transitional tripolar intermediate.

It has been suggested that the spread of a mobile element through a population can be facilitated by increasing the probability of sex in its host Hickey The male-specific region of the human Y chromosome is a mosaic of discrete sequence classes.

In a similar way, the G-specific probe showed predominant binding to terminally located repetitive blocks on a few other chromosomes. Supplementary Table 2 Sequence contigs and gaps on the human X chromosome. In two cases, sequences had been misassembled owing to long and highly similar repeats.

  • Sexual identity is governed by sex chromosomes in plants and animals, and by mating type MAT loci in fungi.
  • There is tremendous sexual dimorphism in human genetic disease susceptibility, progression, and drug response. It is thus alarming that most genome-wide association studies exclude the most sexually dimorphic regions of our genome, the sex chromosomes.
  • Throughout mammalian evolution, recombination between the two sex chromosomes was suppressed in a stepwise manner.

Studies of mutations in model organisms and of human haplotype patterns are leading to a clearer understanding of how meiosis has adapted from yeast to humans, the genes that control the dynamics of chromosomes during meiosis, and how meiosis is tied to gametic success. Yang, F. Chromatid An identical copy of a chromosome that is created through DNA replication.
