meiosis Flashcards
meiosis
a form of cell division that produces gametes
interphase
cell grows and replicates DNA
prophase 1
chromosomes condense and align with their homologous pairs.
crossing over occurs by transferring genetic information
metaphase 1
chromosome align randomly along the equator in their homologous pairs
anaphase 1
Homologous chromosomes are pulled away to opposite poles.
telophase 1
two nulei form as well as a cleavage furrow
prophase 2
spindles from and chromosomes condense
metaphase 2
chromosome align along the middle in a single file
anaphase II
sister chromatids are separated and pulled to the opposite sides of the cell
telophase 2
two nuclei form so have an end result of four new cells and a cleavage furrow is created.
cytokinesis/interkinesis
where two separate haploids form. Some cells may rest here, others go straight into meiosis II.
gametogenesis
where haploid cells become gametes
what does meiosis I begin and end with
begins with a diploid parent cell and ends with two haploid daughter cells.
what is the end result of Meiosis II
four haploid daughter cells.
what process creates the most genetic diversity
crossing over between homologous pairs
