Example sentences for: equational

How can you use “equational” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • In the absence of PSS, which does not occur at significant levels in rec12 mutants [ 52 ] , such mixed segregation patterns can only be generated by a combination of errors in both reductional and equational segregation.

  • PCS of homologous chromosomes and sister chromatids prior to establishing proper kinetochore-spindle attachment during meiosis I increases the probabilities of both homologues going to the same pole and of equational division of sister chromatids during anaphase I. Upon normal fertilization, MII oocytes with an additional chromosome result in trisomic zygotes; whereas oocytes containing an extra chromatid would be expected to produce 50% trisomic zygotes due to random segregation during anaphase II.

  • In meiosis I (MI) homologous chromosomes segregate from their partners in a reductional division, and during meiosis II (MII) sister chromatids segregate from one-another in an equational division similar to mitosis.

  • We therefore propose that Rec12 protein mediates a signal, strictly dependent upon its active site tyrosine, that is required for the equational division of MII.

  • This role for Rec12 in equational chromosome segregation may be conserved, as spo11 mutants of Sordaria macrospora also exhibit frequent MII nondisjunction (S.
