Features of a chromosome
What is the function of a telomere?
What is the function of a centromere?
From Figure 13.6, pg. 245, Human Genetics 6th edition by R. Lewis
Human chromosomes 1-22 are AUTOSOMES. We inherit one set from Mom and one set from Dad.
The X and Y chromosomes are SEX CHROMOSOMES. We also inherit these from our parents. Male offspring inherit one X and one Y. Female offspring inherit two X chromosomes.
Mitosis - (pronounced my-toe-sis) a process that divides duplicated genetic material in the nucleus plus cytokinesis (division of the cell) to produce two identical daughter cells
Here is a link to the Biology Project at the University of Arizona with a figure and animation depicting a cell undergoing mitosishttp://www.biology.arizona.edu/cell_bio/tutorials/cell_cycle/cells3.html
Meiosis - (pronounced my-o-sis) a process to convert a diploid cell to a haploid gamete, and cause a change in the genetic information to increase diversity in the offspring
Here is a link to the Biology Project at the University of Arizona and a tutorial on meiosis:http://www.biology.arizona.edu/cell_bio/tutorials/meiosis/main.html
Vertical transmission of genetic informationMost higher eukaryotes propagate through sexual reproduction that forms a new individual from two haploid sex cells (gametes).
Horizontal transmission of genetic information - will cover in detail next week
