Depends on the country. In Sweden, The UK (and Commonwealth realms) The Netherlands, Norway the law as it stands means the eldest child regardless of gender inherits the throne. In Spain, Tonga and Thailand the law still gives the throne to the eldest son while giving the daughters succession rights after all their brothers and their descendants.
In Jordan, Morroco and all other Islamic kingdoms female succession is explicitly prohibited.
Depending on the law of succession of that country. Some countries only allow males to ascend the throne or are first in line ahead of their elder and younger sisters. While in other countries the law can be where the heir is the eldest child regardless of gender.
