Stages of Meiosis

Vocabulary flashcards covering key concepts and definitions related to the stages of meiosis.

Prophase 1

The chromosomes condense, the nuclear envelope breaks down, homologous chromosomes pair up, and crossing over occurs.

Metaphase 1

Homologous chromosomes line up on the equator and attach to spindle fibers by their centromeres, with independent assortment occurring.

Anaphase 1

Homologous chromosomes are pulled apart to opposite sides of the cell, with centromeres remaining intact and independent segregation taking place.

Telophase 1

Separated chromosomes reach opposite poles, forming a nuclear envelope around each set and resulting in two haploid nuclei.

Prophase 2

The chromosomes condense, the nuclear envelope breaks down, and centrioles move to opposite poles while spindle formation occurs again.

Metaphase 2

Chromosomes line up on the equator attached by their centromeres, with independent assortment of chromatids occurring.

Anaphase 2

The centromere splits and chromatids are pulled apart to opposite poles of the cell, leading to independent segregation of chromatids.

Telophase 2

Separated chromosomes reach opposite poles and a nuclear envelope forms around each of the four sets of haploid chromosomes.
