During meiosis, homologous anaphase I
chromosomes separate at
__________.
If a cell begins meiosis with a 2n Prophase I is the initial stage of meiosis,
(diploid) number of 16, how many when
chromosomes are there in the cell duplicated chromosomes first become
at visible but
prophase I? no division of chromosomes or cell division
has yet
occurred; so, 16 chromosomes (the diploid
number) are present. if the diploid number
of
chromosomes is 16, then each haploid
daughter
cell would contain 8 chromosomes.
If a cell begins meiosis with a 2n 8
(diploid) number of 16, how many
chromosomes are there in each
cell
at metaphase II?
,If a cell has 30 chromosomes The purpose of mitosis is to turn a single
before parent
mitosis, how many does each cell into two genetically identical daughter
daughter cell have afterward? cells.
Therefore, if the parent cell has 30
chromosomes,
then each daughter cell will also have 30
chromosomes after mitosis
In humans, meiosis produces cells Meiosis is referred to as reduction division
that are __________. because
it results in cells that are haploid; the
resulting
cells are specialized sex cells called
gametes.
Which of the following is the last TELOPHASE
stage of mitosis?
Which of the following terms Nondisjunction
describes a failure of
chromosomes
to sort properly during meiosis?
Diploid cells become haploid Meiosis I
during
__________.
In meiosis II, __________. sister chromatids are separated into
different
daughter cells
,Crossing over between Crossing over between homologous
homologous chromosomes
chromosomes normally occurs normally occurs during prophase I.
__________.
a laboratory technique that a karyotype
produces
an image of an individual's
chromosomes
Plant cells divide by __________. mitosis followed by cytokinesis by cell
plate
formation
Plant cells nuclear division occurs through
mitosis. Their cytoplasm is divided through
cytokinesis by cell-plate formation.
Why are no two gametes exactly Each gamete has a different combination
alike genetically? of
parental chromosomes that is the result of
both
crossing over and independent
assortment.
, A human skin cell, in prophase of A sister chromatid is one of the two
mitosis, contains 46 identical DNA
chromosomes. molecules that make up a duplicated
How many chromatids does it chromosome.
contain in total? A cell in prophase of mitosis has already
undergone chromosomal duplication (DNA
replication). Each chromosome will consist
of a pair
of sister chromatids. Therefore, if the cell
has 46
chromosomes, there will be a total of 92
chromatids.
Which of the following is true It involves pairing up of homologous
about chromosomes.
prophase I?
If a cell begins meiosis with a 2n The correct answer is 16 because,
(diploid) number of 16, how many although the
chromosomes are there in the cell homologous chromosomes are separated
at during
anaphase I? anaphase I, telophase I and cytokinesis
have not
yet occurred to produce the two haploid
daughter
cells that are the final product of meiosis I.
Which of the following is true Meiosis II is the second division of meiosis,
about and it
meiosis II? results in the production of four haploid
cells.
