Chromosomes PowerPoint Presentations - PPT
diploid. Sex cells (gametes/germ cells) have only one set of chromosomes . . = . haploid. . That means when fertilization . occurs, the new individual will. have the correct number of chromosomes..
The Chromosome Theory of Heredity. Mutations. Regulation of Gene Expression. Objectives. State the chromosome theory of heredity. Explain how gene linkage affects inherited traits. Describe the process of crossing-over and explain how it increases genetic variety.

in Chimps and Humans. are Horrendously Different. Paul Giem. Loma Linda, CA. Y Chromosomes in Chimps and Humans. The common chimp (Pan troglodytes) and human Y chromosomes are "horrendously different from each other", says David Page of the Whitehead Institute for Biomedical Research in Cambridge, Massachusetts.
Karyotypes. To find what makes us uniquely human, we have to explore the human genome. . A . genome. is the full set of genetic information that an organism carries in its DNA.. A study of any genome starts with chromosomes, the bundles of DNA and protein found in the nuclei of eukaryotic cells. .
Mitosis vs. Meiosis . Mitosis. One division. 2 diploid daughter cells. Identical to parent cell. Mitosis. Two divisions. 4. haploid daughter cells. Genetically different from. parent cell. http://highered.mcgraw-hill.com/sites/0072495855/student_view0/chapter28/animation__how_meiosis_works.html.

Quote: . “. Team Competition. The Cell Cycle. Why the cell must divide:. Reason 1: . The cell only contains one copy of DNA to serve as the instructions for everything that occurs in the cell. If the cell were too large it would not be capable of providing instruction for all necessary functions..
