Meiosis is the process through which sex cells, or egg and sperm cells, are produced in multicellular organisms. This process is divided into two phases—meiosis I and meiosis II.
The picture below shows one stage that occurs during meiosis I.
What is the name of this phase and what occurs during this phase?
A.
Metaphase I; during this phase, homologous chromosome pairs line up in the middle of the cell.
B.
Metaphase II; during this phase, homologous chromosomes line up in the middle of the cell.
C.
Anaphase II; during this phase, homologous chromosomes separate, and sister chromatids are pulled apart.
D.
Anaphase I; during this phase, homologous chromosome pairs separate, but sister chromatids remain attached to each other.
