💡 Big idea: The structure of chromosomes and patterns of inheritance determine how genetic variation and disease risk pass from parent to child.
- 0-5 minWarm-up: sketch what you think a stained chromosome spread looks like.
- 5-30 minTeacher-led notes: chromosome number, autosomes, sex chromosomes, karyotype construction.
- 30-50 minNotes continued: aneuploidy examples, dominant/recessive/carrier definitions, pedigree reading.
- 50-72 minPLTW online activity on chromosomal abnormalities (individual, self-paced).
- 72-80 minExit check: label a blank karyotype diagram with three correct annotations.
- • Notes today are the backbone for Wednesday's hands-on karyotype analysis.
- • Pay attention to how scientists actually read a karyotype in a clinical lab.
- • The WebXam 072110 Biotechnology strand tests chromosome structure and inheritance directly.
- • Finish the PLTW online activity before the period ends so Wednesday's lab makes sense.
- 1Annotate teacher notes on chromosome number, autosomes, and sex chromosomes.
- 2Diagram how a karyotype is built from a stained metaphase spread.
- 3Distinguish aneuploidy (such as trisomy 21) from normal diploid karyotypes.
- 4Define dominant, recessive, and carrier as used in a pedigree.
- 5Complete the assigned PLTW online activity on chromosomal abnormalities.
- • Correctly label autosomes, sex chromosomes, and one trisomy on a karyotype.
- • Submit the PLTW online task with all responses complete.
- • A karyotype organizes chromosomes by size and centromere position to reveal numerical abnormalities.
- • Dominant and recessive alleles follow predictable inheritance patterns visible in pedigrees.
- • Aneuploidy, such as trisomy 21, arises from nondisjunction during meiosis.
Your PLTW work today
Unit 2.2 to 2.3: Chromosomal abnormalities, genetic risk, family evidence, diagnosis from mixed data. · Karyotype and inheritance notes
Day 2 of this lesson. Open this exact section in myPLTW (reached through Schoology), then do the work below.
Do this: Open myPLTW, navigate to Lesson 2.2 Decoding a Diagnosis, and find the chromosomal abnormalities online activity.
Complete all questions and submit within myPLTW before end of period.
You submitted the bioethics reflection Monday. Today finish the full chromosomal abnormalities activity so Wednesday's karyotype lab makes sense.
Show the completion screen or checkmark to the teacher before packing up.
All PLTW activities are completed inside the PLTW course environment — this page only gives direction. Submit producibles on Schoology.
Today's PLTW tracker
Check things off as you work, then submit. This tells Mr. Mendoza how you're doing so he can help the class. It does not replace turning in your producible on Schoology.

Open myPLTW, navigate to Lesson 2.2 Decoding a Diagnosis, and find the chromosomal abnormalities online activity.
You submitted the bioethics reflection Monday. Today finish the full chromosomal abnormalities activity so Wednesday's karyotype lab makes sense.
This is how Mr. Mendoza sees the class keeping pace with PLTW. Be honest, it only helps if it is accurate.
