Lock 1: Chromosome Code
Correct Scientific Name: Nondisjunction
Sentence Stem: "This error is called nondisjunction because chromosomes fail to separate properly during meiosis, resulting in cells with extra or missing chromosomes."

Down Syndrome
Patient B
Turner Syndrome
Patient C
Klinefelter Syndrome

Correct Mutation(s): Deletion and Insertion
Sentence Stem: "A frameshift occurs when a nucleotide is added or deleted, shifting the triplet reading frame and changing all codons downstream."
Lock 4: Inheritance Mystery
Final Probability: 25% (or 1/4)
Sentence Stem: "The probability is 25% because there is a 1 in 4 chance of a son inheriting the affected X allele (XhY) from the carrier mother."

1. Chromosomal Error Analysis
Correct Concept:
Students should explain that nondisjunction is the failure of chromosomes to separate properly during meiosis. This results in gametes having an abnormal number of chromosomes (aneuploidy).
Down Syndrome: Caused by trisomy 21 (3 copies of chromosome 21).Turner Syndrome: Caused by monosomy X (only 1 X chromosome).
2. Mutation Severity
Correct Concept:
An Insertion (or deletion) causes a frameshift mutation. This shifts the entire triplet reading frame of the DNA, changing every amino acid in the protein sequence following the mutation. A Substitution only affects a single codon and may even be a "silent" mutation (no change to amino acid).
3. Inheritance Patterns
Correct Answer: 0% Probability
Reasoning: For X-linked recessive disorders, a father passes his Y chromosome to his sons and his X chromosome to his daughters. Therefore, a father cannot pass an X-linked disorder to his son.
Grading Protocol
Score these exit tickets based on conceptual accuracy rather than perfect terminology. Students who correctly identify the "frameshift" mechanism or the specific chromosome counts for disorders have mastered the core genetic breach protocols.
