• A) \(2.6 \times 10 ^ { - 13 } \mathrm {~m}\)
• B) \(3.5 \times 10 ^ { - 13 } \mathrm {~m}\)
• C) \(3.9 \times 10 ^ { - 13 } \mathrm {~m}\)
• D) \(3.1 \times 10 ^ { - 13 } \mathrm {~m}\)

Definitions:

Dosage Compensation

A genetic mechanism that balances the dose of X chromosome gene expression between males and females in some species.

Nondisjunction

An error in cell division where chromosomes do not separate properly, leading to gametes with an abnormal number of chromosomes, potentially causing genetic disorders.

Abnormal Cells

Cells that have experienced changes in structure or function, often associated with diseases or conditions.

Nonhomologous Chromosome

Chromosomes that are not matching or similar in structure and gene composition; typically refers to the chromosomes that are not sex chromosomes.
