Natural selection means that the organisms better adapted to their environment, that is, they have developed the right characteristics/skills/response to the external ambient, have higher chance to survive, making the next generations genetically inherit such acquired surviving characteristics.
These generations will thus have a higher chance of survival, making these species being "naturally selected" as survivors, while those who haven't or are slower in this process, have a higher risk of elimination.
Sex linked inheritance usually occurs on the X chromosome. Males have one X, meaning if they receive the specific sex linked gene, they will have the trait. However for a female to possess the trait, she must receive 2 X chromosomes for that trait.
