Text: Superfecundation is the fertilization of two or more ova from the same cycle by sperm from separate acts of sexual intercourse, which can lead to twin babies from two separate biological fathers. The term superfecundation is derived from fecund, meaning the ability to produce offspring. Heteropaternal superfecundation refers to the fertilization of two separate ova by two different fathers. Homopaternal superfecundation refers to the fertilization of two separate ova from the same father, leading to fraternal twins. While heteropaternal superfecundation is referred to as a form of atypical twinning, genetically, the twins are half siblings. Superfecundation, while rare, can occur through either separate occurrences of sexual intercourse or through artificial insemination.

Text: An open primary is a primary election that does not require voters to be affiliated with a political party in order to vote for partisan candidates. In a traditional open primary, voters may select one party's ballot and vote for that party's nomination. As in a closed primary, the highest voted candidate in each party then proceeds to the general election. In a nonpartisan blanket primary, all candidates appear on the same ballot and the two highest voted candidates proceed to the runoff election, regardless of party affiliation. The constitutionality of this system was affirmed by the Supreme Court of the United States in 2008, whereas a partisan blanket primary was previously ruled to be unconstitutional in 2000. The arguments for open primaries are that voters can make independent choices, building consensus that the electoral process is not splintered or undermined by the presence of multiple political parties.

Question: can you vote for both parties in an open primary?
