Genetic Variation in Chromosome Pairing
1965Publisher Summary This chapter discusses the genetic variation in chromosome pairing. Alterations in the behavior of chromosomes at meiosis are known to result from genetic variation as well as from differences in several environmental factors. The operation of selection on genetically controlled variation in the chromosomal phenotype is responsible ...

Initiation of homologous chromosome pairing during meiosis
Biochemical Society Transactions, 2006Following pre-meiotic DNA replication, homologous chromosomes must be paired and become tightly linked to ensure reductional segregation during meiosis I. Therefore initiation of homologous chromosome pairing is vital for meiosis to proceed correctly. A number of factors contribute to the initiation of homologous chromosome pairing including telomere ...

Chromosome pairing and induced exchange in Drosophila
Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis, 1965Abstract Fragments of Y chromosomes were induced by irradiating attached-X Drosophila melanogaster females carrying a doubly marked Y chromosome, and detected by loss of one of the Y markers. Slightly more than half of the 55 fragments recovered showed linkage of fourth chromosome markers, implying a high frequency of association of Y and fourth ...

The Analysis of Chromosome Pairing
1975In respect to chromosome pairing, two situations may be distinguished: non-competitive pairing, in which only two possible partners are available, and competitive pairing, where more than two potential partners are available, but where nevertheless only two at a time can finally pair sufficiently effectively to form a chiasma.
