The cell cycle process whereby spindle microtubules become physically associated with a chromosome during meiosis. The alignment of chromosomes at the metaphase plate, a plane halfway between the poles of the meiotic spindle, during meiosis I. The process by which genetic material, in the form of chromosomes, is organized into specific structures and then physically separated and apportioned to two or more sets during M phase of the meiotic cell cycle. The cell cycle process whereby replicated homologous chromosomes are organized and then physically separated and apportioned to two sets during the first division of the meiotic cell cycle. Each replicated chromosome, composed of two sister chromatids, aligns at the cell equator, paired with its homologous partner; this pairing off, referred to as synapsis, permits genetic recombination. One homolog (both sister chromatids) of each morphologic type goes into each of the resulting chromosome sets. A cellular process that is involved in the progression of biochemical and morphological phases and events that occur in a cell during successive cell replication or nuclear replication events. The process by which spindle microtubules become physically associated with a chromosome. The cell cycle process whereby chromosomes are aligned at the metaphase plate, a plane halfway between the poles of the meiotic spindle, during meiosis. The cell cycle process whereby the sister centromeres of one chromosome attach to microtubules that emanate from the same spindle pole, which ensures that homologous maternal and paternal chromosomes are pulled in opposite directions at anaphase of meiosis I.
