Question		Answer
nondisjunction start learning		results in a new cell having too many or not enough chromosomes
What is the purpose of sexual reproduction? start learning		genetic variation
What results in genetic variation? start learning		meiosis
what does crossing over produce? start learning		genetic variation by producing new combination of alleles (genes)
Meiosis produces...? start learning		4 haploid cells
Mitosis produces...? start learning		2 diploid cells
What must occur before a cell can divide? start learning		DNA replication
What divides the cytoplasm? start learning		cytokinesis
What is mitosis responsible for? start learning		growth and development
what role does the centromere play in cellular reproduction? start learning		it is the area of attachment for chromatids
Which part of the cell cycle is when new cells are formed? start learning		mitosis
What is the end result of asexual reproduction? start learning		2 cells
What is the longest phase of the cell cycle? start learning		interphase
What results when cell division happens at a high rate? start learning		cancer
What is the correct order for cellular division start learning		Prophase, Metaphase, Anaphase, Telophase
G1, S, and G2 phase are a part of? start learning		interphase
Cytokinesis (def) start learning		the last stage, the cytoplasm splits into half forming into two cells
interphase start learning		consists of G1->S1->G2 phases
metaphase start learning		chromosomes line up in the center of the cell and spindle fibers attach to chromosomes from centrioles
S phase start learning		DNA and chromosomes are copied
telophase start learning		chromosomes unravel into chromatin to provide DNA for new cell
prophase start learning		chromosomes condense and nucleus and centrioles move to opposite poles
anaphase start learning		chromosomes are pulled apart and sister chromatids are separated
G1 start learning		the cell grows rapidly and replicates
G2 start learning		replicates the rest of the organelles
cell cycle start learning		the never-ending process by which all cells in your body replicate
haploid start learning		half the number of chromosomes
diploid start learning		the full set of chromosomes
gamete start learning		reproductive cells
zygote start learning		a diploid, when two gametes unite together in fertilization
mitosis start learning		how eukaryotes replicate and divide; major part of the cell cycle
meiosis start learning		asexual reproduction, a process that reduces the number of chromosomes by half
fertilization start learning		when two gametes unite together to form a zygote
asexual reproduction start learning		one parent cell splits into two daughter cells that are identical to the parent cell
sexual reproduction start learning		two parents make one or more offspring that are genetically different than the parents
