Meiosis Flashcards
Meiosis
Reproduction of gametes zygote
Prophase I
Parent cell’s nuclear membrane begins to disappear, spindles form
Metaphase I
Chromosomes line up with homogonous chromosomes. Crossing over may occur
Anaphase I
Homogonous chromosomes are separated, so one of each goes to either side
Telophase I
Cell separates, cytokinesis occurs
Prophase II
Almost simultaneous with Telaphase I; new spindles form and attach to centromeres
Metaphase II
Chromosomes line up again, and some crossing over may occur
Anaphase II
Sister chromatids pulled apart at centromeres, towards poles
Telophase II
Cell separates, nuclear membranes form, cytokinesis occurs
Interphase
Diploid sex cells have double the normal chromosomes necessary
