Example sentences for: meioses

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

  • A 250-fold reduction in recombination would leave less than 0.1 crossovers per chromosome, so all three chromosomes in most of the rec12 mutant meioses are achiasmatic.

  • Rec12 and its active site tyrosine are required for chiasmatic meioses

  • At present, two hypothetical mechanisms by which a Rec12-dependent signal affects MII are proposed: First, Rec12-dependent (recombination-dependent) signals might trigger a block after MI, thereby allowing cells to skip a frequently irregular MII division [ 39 ] . However, the majority of the rec12 mutant meioses show evidence of two meiotic divisions (Figure 3) and many of the meiotic diploids exhibit mixed MI and MII missegregation patterns for centromere linked markers on the three different chromosomes (Table 2).

  • Thus, those meioses did not exhibit simple MI nondisjunction, because 100% of diploids arising from MI nondisjunction would be heterozygous at the centromeres (Figure 5B).

  • However, only about 50% of diploid meiotic products from rec12-D15 (null) mutant meioses were heterozygous for centromere linked markers (Figure 5E), indicating that some fraction of the products were derived from precocious separation of sister chromatids (PSS) and/or MII nondisjunction (Figure 5C, 5D).
