Meiosis & Mitosis EXAM PREP WITH
COMPLETE SOLUTION
Gametes - =Sex cells
Egg - =Females sex cell
Sperm - =Male sex cell
Haploid number - =Number of chromosomes found in a gamete
Diploid Number - =Number of chromosomes found in the body cells of an organism
The diploid number is twice its haploid number
Meiosis - =type of cell division that produces gametes
Polar bodies - =In meiosis, one cell receives most of the cytoplasm, making it much larger than
the peter three cells. The large cell becomes the female gamete or an egg cell, the three smaller
cells are called polar bodies and are not involved in sexual reproduction
If something goes wrong during Meiosis - =The parent cell does not separate evenly, causing a
daughter cell to have an abnormal number of chromosomes. If this gamete joins with a normal
gamete during sexual reproduction, the new cell that forms lacks the diploid number. An
organism that develops from this cell will have a genetic disorder.
In what type of organs are cells that enter Meiosis I found? - =sex cells
Considering what you know already know about mitosis in cells, what event must take place
during interphase before a cell precedes to division? - =DNA replication
, What two structures make up a single replicated chromosome? - =sister chromatids
How many replicated chromosomes does the cell contain during prophase? - =4
At which stage in Meiosis I do the pairs of homologous chromosomes come together? - =Late
Phase 1
Once the chromosomes have formed a pair, what are they called? - =Tetrads
At the end of meiosis I, two cells have been produced. How many replicated chromosomes are
in each of these cells? - =2
Cells with a full set of chromosomes are referred to as diploid or 2n, whereas cells with half the
chromosomes are haploid or n. At which stages of meiosis I are the cells diploid and at which
stages are they haploid? - =Diploid: Prophase, Metaphase, Anaphase
Haploid: Telophase II
Considering the genetic makeup of the homologous pairs, will the cells at the end of telophase I
be genetically identical to each other? - =No, they will not be identical because the alleles on
each pair are not identical and the homologous pairs separate.
Where did each of the cells come from that started Meiosis II? - =Meiosis I
In meiosis I, during anaphase I, which structures separated- homologous chromosomes or sister
chromatids? - =Homologous chromosomes
In Meiosis II, during Anaphase II- which structures separated- homologue chromosomes or
sister chromatids? - =Sister chromatids
