meiosis

recommend writing it out

what stage is this?

• chromosomes become visible as they condense and thicken

prophase I

what stage is this?

• chromosomes line up with homologous pairs

prophase I

what stage is this?

• “crossing over” occurs

prophase I

what stage is this?

• homologous pair lines up and exchanges genetic info

prophase I

what stage is this?

• recombinant chromosomes are created

prophase I

Define:

chromosomes that are approximately the same size and contain the same types of genes in the same lcoations

homologous pairs

define:

• process where homologous pairs trade their genetic info with each other

crossing over

define:

type of chromosome that contributes genetic variation with siblings

recombinant chromosome

what stage is this?

• homologous pair of chromosomes go to center of cell

metaphase I

what stage is this?

• chromosomes are pulled away by spindle fibers towards opposite sides

anaphase I

what stage is this?

• there are two newly formed nuclei

telophase I

what stage is this?

• 2 cells are created through cytokineses

telophase I

define:

• splitting of the cytoplasm

cytokineses

what stage is this?

• where spindles form but there are no homologous pairs of chromosomes and crossing over does NOT occur

prophase II

what stage is this?

• single chromosomes line up in a single file line in the center of cell

metaphase II

what stage is this?

• chromatids are pulled away towards spindle fibers

anaphase II

what stage is this?

• 2 cells are divided into 4 cells

telophase II

the type of cell that are produced are called

haploid cells

cells are (identical or nonidentical)

nonidentical
