Transcript Meiosis Review

Mitosis/Meiosis
How are they
different?
The exchange of DNA between the
chromatid arms on homologous
pairs is called ________________
Crossing over
This type of cell division
used by bacteria to reproduce
Binary fission
The mixing up of maternal and
paternal chromosomes as they
move apart during anaphase I is
called ______________
Independent assortment
This diagram is
showing
Crossing over
_________________
During which phase does
this happen?
PROPHASE I of
meiosis
Is it MITOSIS or MEIOSIS?
mitosis
Makes 2 daughter cells ______________
meiosis
Makes haploid cells _______________
Divides twice but
meiosis
copies DNA once __________________
mitosis
Used to repair injuries ______________
Is it MITOSIS or MEIOSIS?
Meiosis
Makes 4 daughter cells ______________
mitosis
Makes diploid cells _______________
mitosis
Copies DNA every __________________
time it divides
meiosis
Used to make gametes ______________
Is it MITOSIS or MEIOSIS?
Makes 2n cells ______________
mitosis
Crossing over happens _______________
meiosis
mitosis
Used when organisms _________________
grow bigger
meiosis
Used in sexual reproduction ___________
Is it MITOSIS or MEIOSIS?
meiosis
Testes and ovaries do it ____________
mitosis
Body cells do it _______________
meiosis
Crossing over happens ____________
Divides twice ______________
meiosis
in a row
Is it MITOSIS or MEIOSIS?
meiosis
Independent assortment_____________
happens
mitosis
Divides just once_______________
Makes cells identical
to parent cell

Type of cell
division shown
meiosis
Type of cell division
shown
mitosis
Tell one reason why a cell would
do this Grow organism bigger
Repair injuries
Replace worn out cells
Producing offspring without using
sperm or eggs in which the DNA
comes from only 1 parent
Asexual reproduction
Type of reproduction in which
offspring are produced by
combining the genetic material
from 2 parents
Sexual reproduction
A cell with only one copy of each
Haploid OR 1n
chromosome is called ___________
A cell which has 2 copies of every
chromosome is called _____________
diploid
OR 2n
Type of division that makes daughter
cells which are different from the
parent cell and different from each other
meiosis
Phase in which INDEPENDENT
ASSORTMENT happens
Metaphase I
Name 2 ways the DNA in cells gets
recombined in new ways during
meiosis
Crossing over OR
independent assortment
Phase during which SYNAPSIS happens
Prophase I
Phase in which CROSSING OVER
happens
Prophase I
Tell one phase that is different in
meiosis than in mitosis
Prophase I- Homologouse chromosomes
pair up & crossing over occurs
Anaphase I- independent assortment
Metaphase I- pairs line up together
