KEY- Case Study: Cross Dressing or Clicker Questions: Short Answer Questions: B (an irregular menstrual is normal for External sex organs (Genitalia), body many female athletes) hair, pelvis, breast tissue, body A (XY chromosomes) curvature, concentrations of sex A hormones, internal reproductive C organs, sex chromosomes, etc. B (Meiosis I = reduction division) Gametes are haploid (they contain half D (Anaphase II) of the amount of genetic information as D diploid somatic cells). C XX (SRY+) is male, XY (SRY-) is female. C (crossing over increases genetic During meiosis, crossing over occurred variation) between the X and Y sex chromosomes, Your opinion… below the “tip” of the chromosome. Your opinion… This crossing over included the SRY gene. The SRY gene which is normally on the Y chromosome is now on the X chromosome. This would result in gametes that are X (SRY+) and Y (SRY-). If these gametes resulted in fertilization, the individuals would be XX (SRY+) male or XY (SRY-) female.
