crossing over occus in
meiosis
meiosis starts with___ cell and resultes in the formation of ___ cells
one diploid….four haploid
The cell cycle results in the production of ____
two cells, each with the same amount of genetic material and the same genetic information
During metaphase 1
homologous chromosomes line up in the middle of the cell
which of the following is a stage of mitosis
telophase
the diploid number of chromosomes in a goldfish is 96. what is the haploid number
48
bacteria cells divide be
simple cell cycle
during telophase
the events of prophase are reverse
if you had skin cells dividing in your body, they would divide by
mitosis
which of the following is the best description of the events of anaphase 1?
homologous chromosomes randomly separate and migrate to opposite poles
in meiosis, sister chormatids migrate to the opposite poles during
anaphase II
cytokinesis typically occurs during the ___ stage of mitosis
telophase
which of the following stages of the cell cycle makes up interphase
all of the above
which of the following occurs during prophase
the mitotic spindle begins to form
chromosomes that do not determine the sex of an individual are called
autosomes
DNA replication occurs in the ___ stage of the cell cycle
S
In meiosis, homologous chromosomes line up at the equator in a tetrad formation during
Metaphase I
In mitosis, chromatids move to opposite poles during
Anaphase
In meiosis, whole chormosomes move to the opposite poles during
Anaphase I
The proper sequence of the phases of mitosis, from beginning to end is
prophase, metaphase, anaphase, telophase
Upon completion of telophase I and cytokinesis, the is (are)___ cell(s)
two haploid
a somatic cell would divde bey
mitosis
one difference between mitosis and meiosis is
mitosis produces cell genetically identical to the parent cell, but meiosis does not
in prophase
chormosomes become visible
