Along with the X chromosome, it is part of the XY sex-determination system, in which the Y is the sex-determining chromosome because the presence of the Y chromosome causes offspring produced in sexual reproduction to be of male sex.en.wikipedia.org/wiki/Y_chromosomeY-DNA refers to the DNA found on one of the sex chromosomes, the Y-chromosome. (The other sex chromosome is the X chromosome.) Sex chromosomes usually come in pairs and play a role in development, especially of primary and secondary sex characteristics.www.ancestry.com/c/dna-learning-hub/y-dnaA Y chromosome DNA test (Y-DNA test) is a type of genealogical DNA test used to trace a man's patrilineal ancestry through his biological father's line.

Wikipedia text under CC-BY-SA license Y chromosome - Wikipedia
Many ectothermic vertebrates have no sex chromosomes. If these species have different sexes, sex is determined environmentally rather than genetically. For some species, especially reptiles, sex depends on the incubation temperature. Some vertebrates are hermaphrodites, though hermaphroditic species are most commonly sequential, meaning the organism switches sex, producing male or female gametes at different points in its life, but never producing both at the sa…
