What is the term for the chromosomal alteration where a segment of genes is flipped, reversing their sequence within the chromosome?

Explanation

The correct answer is C: Recessive gene. However, the description given in the question actually corresponds to 'Inversion,' which is when a chromosome segment reverses its gene order. 'Recessive gene' refers to a gene whose traits are masked by dominant alleles and is unrelated to gene order changes.
