Gene-ius 4th/5th grade

Comment: Hello…I’m coaching 4th grade Gene-ius event. I have following questions about karyotype analysis:
1. Should the kids memorize all of the 23 chromosome pattern. Will they be asked to number/ arrange chromosome?
2. Will you provide the human chromosomes-identification key for reference during the event?

Response: Teams should not memorize the chromosome patterns.  If asked to arrange they would be given the human chromosome key.  It is possible that they may be given actual stained human chromosomes and asked to match them based on centromere position and banding pattern but they would not be expected to identify which human chromosome it was without a key.
