Finally, what advice would offer to parents who believe they are at high risk of having a child with a chromosomal or genetic disorder.

Examples of chromosomal disorders: sex chromosome disorders, Down syndrome.
Examples of genetic disorders: Sickle-cell anemia, fragile X syndrome, PKU
Advice: Answers will vary. Students might recommend genetic counseling, prenatal screening/diagnosis, or to act in supportive and encouraging ways toward the child once he/she is born to increase the likelihood of favorable development.
