1. Week 8 Vocab Definitions

2. Meiosis
A type of cell division that produces gametes for sexual reproduction and allows for variation
Homologous Chromosome
Chromosomes that pair up during meiosis containing genes for the same traits

3. Crossing Over
The exchange of genetic material between homologous chromosomes that is a source of variation
Nondisjunction
Is the failure of homologous chromosomes to separate properly during meiosis
Haploid
Gamete cells that contain only half of the chromosomes normally found in the organism

4. microtubules that move chromosomes during cell division.
Diploid
Body cells that contain pairs of the chromosomes normally found in the organism
Spindle Fiber
microtubules that move chromosomes during cell division.
Gamete
Sex cell (egg or sperm)

5. Somatic cell
Body cell (muscle, nerve, blood, skin, etc.)
Locus
the specific location of a gene or DNA sequence or position on a chromosome
