Biology · CELL CYCLE AND CELL DIVISION

Examine the stage of Meiosis I labelled as 'Anaphase I' in the provided figure. What is the fundamental behavior of chromosomes depicted at this stage?

Centromeres split simultaneously and sister chromatids separate
Bivalent chromosomes line up as single chromatids along the equatorial plate
Chromosomes decondense completely into an uncoiled interphase chromatin state
Homologous chromosomes separate to opposite poles while sister chromatids remain associated at their centromeres

Correct answer · Option 4

Homologous chromosomes separate to opposite poles while sister chromatids remain associated at their centromeres

In Anaphase I of Meiosis I, homologous chromosomes separate toward opposite poles, but sister chromatids remain united at their centromeres.
