Answer:
When homologous chromosomes misalign during meiosis, unequal crossing-over occurs. The result is the deletion of a DNA sequence in one chromosome, and the insertion of a DNA sequence in the other chromosome.
Step-by-step explanation:
- Class of Mutation: Type of Mutation
- Copy number variation: Gene amplification
- Point mutation: Substitution
- Chromosomal mutation: Inversion
A chromosome mutation is an unpredictable change that occurs in a chromosome. These changes are most often brought on by problems that occur during meiosis (division process of gametes) or by mutagens (chemicals, radiation, etc.).
