The spermatid is the haploid male gametid that results from division of secondary spermatocytes. As a result of meiosis, each spermatid contains only half of the genetic material present in the original primary spermatocyte.

Spermatids are connected by cytoplasmic material and have superfluous cytoplasmic material around their nuclei.

When formed, early round spermatids must undergo further maturational events to develop into spermatozoa, a process termed spermiogenesis (also termed spermeteliosis).

The spermatids begin to grow a living thread, develop a thickened mid-piece where the mitochondria become localised, and form an acrosome. Spermatid DNA also undergoes packaging, becoming highly condensed. The DNA is packaged firstly with specific nuclear basic proteins, which are subsequently replaced with protamines during spermatid elongation. The resultant tightly packed chromatin is transcriptionally inactive.

Clifford Smith (born 1974), better known as Mr. Vegas, is a Jamaican dancehall star.

Smith was born in Kingston in 1974. The moniker "Mr. Vegas" was given to Smith by his schoolyard football-mates, who thought that he kicked the ball like a Las Vegas dancer. In his early years as a singjay, Vegas sang covers of Jamaican hits at local parties and shows, and acquired a reputation as a troublemaker. During a scuffle over stolen master tapes, Vegas was hit in the face with a crowbar and had his jaw wired shut for six weeks. Vegas claims that, after hearing Beenie Man's hit "Who Am I", he immediately demanded that his still-healing jaw be unwired, changing his speech pattern but allowing him to practice toasting.

He found fame in 1998 with hits such as "Yu Sure", "Jack It Up", and "Latest News". For his first major hit, Vegas played off of^{[clarification needed]} "Who Am I" to create "Nike Air", which became a huge hit in Jamaica.^{[citation needed]} The next single, "Heads High", followed its success in Jamaica with a chart run in the UK and a #69 peak on the US R&B chart, and Vegas became increasingly in demand as a guest artist by acts such as Sean Paul.^{[citation needed]}
