Homologous chromosomes (bivalents) are aligned at the equatorial plate?

Open in App

Solution

Metaphase I:
Homologous chromosomes are made up of chromosome pairs of approximately the same length, centromere position, and staining pattern, for genes with the same corresponding loci
During the Metaphase I of first meiotic division, homologous chromosomes (bivalents) are aligned at the equatorial plate of the spindle.
Bivalents are attached to the spindle fibres by their centromere.
