The sex of the offspring.
The alleles that are passed from parents to offspring
DNA chromosomes
By observing the proportion of affected offspring and whether males or females are more affected.
Gametes carry genes that determine the sex of an offspring.

yes.
The alleles that are passed from parents to offspring
Yes, the sex of the offspring is determined by the chromosomes contributed by the parents. The female parent always gives an X chromosome, while the male parent can contribute either an X or a Y chromosome, determining whether the offspring will be male (XY) or female (XX).
Units of heredity that are transferred from a parent to offspring and are held to determine some characteristic of the offspring.

No, there is no distinction between male and female sperm. Sperm cells carry genetic material from the male parent and determine the sex of the offspring.
