Human female gametes are called ova and male gametes are called sperm. \\ ii. Mitosis is the type of cell division that is used to produce sex cells. \\ \hline iii. All chromosomes are the same size. \\ \hline iv. Non-homologous chromosomes have the same relative size, position of \\ centromere and stained banding patterns. \\ \hline \begin{tabular}{l} v. Human males possess a pair of \( X \) chromosomes \( (X X) \), whereas human \\ females possess an \( X \) and a \( Y \) chromosome (XY). \\ \hline vi. Sometimes a genetic mistake or mutation can occur that results in more or \\ less of a particular type of chromosome. \\ \hline vii. Differences between the chromosome pair size, shape and banding can be \\ used to distinguish them from each other and to construct a karyotype. \\ \hline viii. Telomeres (caps of DNA on the tip of the chromosome), which enable DNA \\ to be replicated safely without losing valuable information, shorten each \\ time the cell divides. \end{tabular} \\ \hline\end{tabular}
