How To Use Pachytene In A Sentence

-
In wild-type hermaphrodites, germ cells at the dorsoventral flexure exit the pachytene stage of the first meiotic prophase and proceed to diakinesis.
-
Meiotic prophase can be further divided into leptotene, zygotene, pachytene, diplotene, and diakinesis stages defined by the state of chromosome pairing and condensation.
-
This SC karyotype is very similar to karyotypes developed from pachytene chromosome squashes.
-
For F59A1.7, affected worms exhibiting a high frequency of achiasmate chromosomes at diakinesis also had abnormally large nuclei at the pachytene stage, earlier in meiotic prophase.
-

This structural heterozygosity correlates with both a previously described recombination block and cytologically visible unpaired chromosomes at pachytene.
-
A bivalent B chromosome was removed directly from a pachytene slide by a micromanipulator.
-
During pachytene, the chromosomes are less condensed and much longer than in mitotic metaphases.
-
This SC karyotype is very similar to karyotypes developed from pachytene chromosome squashes.
-

-
Homologous chromosomes are fully aligned at the pachytene stage, and germ cells survive to complete meiosis and gametogenesis with high efficiency.
-
Each chromosome is identifiable by its relative length, by the location of its centromere, which is readily observed at the pachytene stage, and by the individuality of the chromomeres strung along the length of each chromosome.
Nobel Lecture The Significance of Responses of the Genome to Challenge
-
