In humans what type of cells undergo Mitosis?
Somatic cells (everything except gametes)

True or false: Interphase is not included in the phases of mitosis.
True: It is however a part of the cell cycle, however occurs prior to Mitosis

Which organelle is responsible for producing the spindle fibers?
Centrioles

What is the definition of cell division?
The process by which one cells divides into two new daughter cells.

Briefly explain what Homozygous dominant, homozygous recessive, and heterozygous looks like in Mendelian Genetics
Homozygous dominant: two dominant alleles represented with upper case letters
Homozygous Recessive: two recessive alleles represented with two lower case letters
Heterozygous: one dominant and one recessive allele

True or False: Environment does not play a role in genetics. Justify your answer.
False: traits such as skin color are dependent on your exposure to UV rays, or certain cancers which also depend on environmental factors

How many Times could your DNA stretch to the sun if we were to straighten out all of the DNA in your cells?
approx 600 times :)

List the Phases of Mitosis in order and explain what happens at each step.
Prophase: nuclear envelop dissolves, chromosomes form
Metaphase: line up at center
Anaphase: pulled to opposite ends
Telophase/cytokinesis: nuclear envelope reforms and cells divide

Compare and contrast Haploid and Diploid...
Haploid: cell that contains only a single set of genes in humans n:23
Diploid: cell that contains two sets of genes in human 2(n): 46

List three of the four Mendelian genetic postulates.
1. Principles of paired Factors (need atleast two alleles)
2. Principles of Dominance: one allele is dominant over the other
3. Law of segregation: alleles keep their identify
4. Law of independent assortment: each characteristic separates independently
