100

What is in an aster formation?
This is how the microtubules/spindle fibers form.

100

What are independent assortment and crossing over?
These are the two ways that genetic variation can occur within a zygote.

100

What is the production of gametes?
The purpose of meiosis.

100

What is tall/below average intelligence?
Name a trait of a person with XYY.

100

What is binary fission?
The name for cell division in unicellular organisms.

200

What is meiosis II?
The division of meiosis that is most like mitosis.

200

What is prophase I?
This is the only phase crossing over occurs.

200

What are non-identical sister chromatids?
In anaphase I, this is separated.

200

What is 45 chromosomes?
This is how many chromosomes a person with Turner’s Syndrome has.

200

What is histone?
The protein that chromatin condenses around.

300

What are somatic/diploid cells?
This kind of cell goes through mitosis.

300

What is within the nuclear envelope/nucleus?
This is the place where crossing over takes place in the cell.

300

What is metaphase I?
When independent assortment occurs.

300

What is Down Syndrome?
People with a trisomy 21 have this.

300

What is synapsis?
Chromosomes undergo this process to form tetrads.

400

What is prometaphase?
During this phase, the spindle fibers attach to the kinetochores.

400

What is 2n/haploid?
This is what the cell becomes when it has been split after meiosis I. (Hint: chromosome count)

400

What are 4 haploid cells?
Cytokinesis in meiosis II results in this many haploid cells.

400

What are Klinefelter Syndrome/XXY and Turner's Syndrome/X0?
People with these sex chromosome disorders are sterile.

400

What is a benign tumor?
A tumor that does not spread and is not cancerous.

500

What are centromeres?
Not only are sister chromatids split in anaphase, but also these.

500

What is chiasma/chiasmata?
The site where Homologous chromosomes are held together when they are lined up on the metaphase plate during independent assortment.

500

What is interphase?
This is a typical phase that meiosis II does not consist of.

500

What is Edward's Syndrome?
This genetic disorder affects almost every organ system.

500

What is the Golgi Apparatus?
The organelle that produces a membranous sac that fuses to form a cell plate in telophase for plant cells.
