Abstract:
The Ae. ventricosa and S. cereale genomes were distinguished at meiosis by the C-banding procedure. Only two plants of the amphiploid Ae. ventricosa-S. cereale were found to exhibit the high degree of asynapsis limited to Aegilops ventricosa genomes. In addition, these genomes showed higher homoeologous pairing than homologous pairing frequencies. These results can be explained by the existence of separate genome-specific control of meiotic pairing between the chromosomes of both species in these synaptic mutant plants.

Meiosis II
The timing and cell division patterns of meiosis differ between males and females. In male meiosis, the centrosomes are part of the formation of the meiotic spindle. However, in oocytes, including that of humans, Drosophila,...

Meiosis I
Prophase I is the most extended and complex step of meiosis I characterized by synapsis, chromosome pairing, and recombination of the homologous chromosomes. This process is facilitated by a proteinaceous structure called the...
