Mitosis Vs Meiosis
how many haploid egg cells do women produce during meiosis? why?

a tetrad
gametes have one BLANK for each BLANK
allele gene
are chromosomes replicated before or after meiosis 1 stats?
before
what are somatic cells?
body cells
G1, G2, S phase, M phase are all parts of the BLANK
cell cycle
what is the series of events that cells go through as they grow and divide?
cell cycle
chromosomes are visible only during BLANK
cell division
what happens during G1?
cell growth
what are the steps of anaphase during mitosis?
centromere's split and the sister chromatids are separated spindle fibers pull individual chromatids toward the poles of the cell
what are the steps of prophase during mitosis?
chromosomes appear nuclear envelope disappears nucleolus disappears centrioles split and travel to opposite poles of the cell spindle fibers begin to form
what are the steps of telophase during mitosis?
chromosomes group together and begin to unravel, turing back into chromatin nuclear envelope begins to reform nucleolus appears again cell membrane begins to pinch in
what is it called when tetrads exchange genetic material?
crossing over
a cell with two complete sets of chromosomes is called a BLANK cell
diploid
mitosis results in the formation of BLANK cells
diploid
when does mitosis occur?
during M phase in cell division
when are gametes produced?
during meiosis
when do chromosomes form tetrads?
during prophase 1 of meiosis
what does the cell do during interphase?

prophase metaphase anaphase telophase
what does N stand for?
represents the number of chromosomes in a gamete
what do the spindle fibers help do?
separate chromosomes
what are gamete cells?
sex cells
what are the steps of metaphase during mitosis?
spindle fibers attach to the centromere between sister chromatids chromosomes line up along the mid-line of the cell
what phase of mitosis usually occurs at the same time as cytokinesis?
telophase
crossing over rarely occurs in mitosis because BLANK rarely form during mitosis
tetrads
what is crossing over?
when chromosomes become altered during meiosis
