Input: Question: Did other scientists keep blending inheritance open for further consideration? Passage 1:A Seattle native, Gordon exhibited an early interest in theoretical physics, especially quantum mechanics and the theory of relativity. His childhood heroes were Albert Einstein, Stephen Hawking, and Richard Feynman. After observing a series of teleportation experiments conducted by the Institute for Experimental Physics at the University of Innsbruck, the transmission of matter became Gordon's obsession. Gordon has no known dependents. He graduated from the Massachusetts Institute of Technology with a Ph.D. degree in Theoretical Physics. His doctoral thesis on the teleportation of matter through extremely dense elements was titled Observation of Einstein-Podolsky-Rosen Entanglement on Supraquantum Structures by Induction Through Nonlinear Transuranic Crystal of Extremely Long Wavelength (ELW) Pulse from Mode-Locked Source Array. Gordon's research into science eventually led him to accept a job offer by the Black Mesa Research Facility, and begin working on a top-secret research project headed by his mentor at MIT, Dr. Isaac Kleiner. He takes up residence at Black Mesa, conducting nuclear and subatomic research in its Anomalous Materials department. Despite his education as a theoretical physicist, the work Freeman is involved with at Black Mesa is of a more experimental nature.
 Passage 2:In the preface, Fisher considers some general points, including that there must be an understanding of natural selection distinct from that of evolution, and that the then-recent advances in the field of genetics (see history of genetics) now allowed this. In the first chapter, Fisher considers the nature of inheritance, rejecting blending inheritance, because it would eliminate genetic variance, in favour of particulate inheritance. The second chapter introduces Fisher's fundamental theorem of natural selection. The third considers the evolution of dominance, which Fisher believed was strongly influenced by modifiers. Other chapters discuss parental investment, Fisher's geometric model, concerning how spontaneous mutations affect biological fitness, Fisher's principle which explains why the sex ratio between males and females is almost always 1:1, reproductive value, examining the demography of having girl children. Using his knowledge of statistics, the Fisherian runaway, which explores how sexual selection can lead to a positive feedback runaway loop, producing features such as the peacock's plumage. He also wrote about the evolution of dominance, which explores genetic dominance. The last five chapters (8-12) include Fisher's more idiosyncratic views on eugenics.
 Passage 3:She was born in Yazıhan and studied cartography and land surveying in Mersin University, before beginning her political career through the Women's Branch of the Party of People's Democracy (HADEP) in 1998. She was vice co-chairperson and Istanbul deputy of the Democratic Society Party (DTP), which she helped to found. She has also worked with international organizations such as UNDP and Amnesty International. She was arrested on 5 November 2006 for alleged membership in the PKK But after she ran as an independent candidate within the Thousand Hopes alliance for the parliamentary elections from prison and after winning a seat in Istanbul with 93,000 votes, was released from custody in July 2007. She was elected to the Turkish Parliament from prison to the surprise of many. In 2013 she was elected Co-Chair of the HDP together with Ertuğrul Kürkçü. In May 2016 she was elected Co-Chair of the Democratic Regions Party (DBP) together with Kamuran Yüksek. On 4 October 2016 she was taken into custody and arrested in November 2016. According to the International Law Bureau the prosecution demands 130 years of imprisonment for terror related charges due to her membership in the legal party Democratic Society Party and 16 statements and speeches she made during meetings and press conferences she held before meetings of the DBP. On the 5 January 2018 she got sentenced to 2 years and three months in prison. On 1 December 2018 she joined Leyla Güven in her hunger strike. In February 2019 she got sentenced to 15 years in prison for being a member of a terrorist organization and making propaganda for a terrorist organization.
