3. Sex Determination People – 46 chromosomes or 23 pairs
•22 pairs are homologous (look alike) – called autosomes – determine body traits
1 pair is the sex chromosomes – determines sex (male or female)
•Females – sex chromosomes are homologous (look alike) – label XX
Males – sex chromosomes are different – label XY

5. Sex-Linked Notes
If a gene is found only on the X chromosome and not the Y chromosome
if the gene is recessive, males only need 1 gene to show trait rather than 2
this is why males show trait more often
Example: R/G Colorblind, male pattern baldness, hemophillia, Duchenne, Muscular Dystrophy
Females sex genes are both XX, homozygous recessive

6. Video Genetics Disorders Gallery Walk
You can use your own device to complete this assignment. The groups must split up the work according to topic and write the information on the Genetic Disorder you all assigned. You will only have 20 minutes to complete the research and fill it out on Chart paper so the other groups can record what you wrote for you groups’ assigned Genetic Disorder.
