| Question | Answer |
| Ovists belief | the homunculus resided in the egg |
| When were animals domesticated? | around 13,000 BCE |
| What is the Theory of Epigenesis? | - all parts of the embryo are present potentially in the egg - the organism evolves by gradual building up and aggregation of these parts |
| Even though the eugenics movement haulted in 1939, when did it stop? | it continued into the 1970s, specifically for the mentally ill and inprisoned. Eventually, 33 state were accused for compulsory sterilization accounting for 60,000 americans being involuntarily sterilized |
| What were the first traits studied in humans? | polydactyly and Hempphilia |
| Who provided the first formal attempt of heredity and variation? | Greek philosophers |
| Describe the classic hemophilia pedigree of Queen Victoria's family. | Victoria's 9 children: 1) Beatrice, carrier, introduced the genes to Spanish royals 2) Alice, carrier, introduced gene to Rus/Prussian royals 3) Leopold, son who died of disease, 4) Edward 7th (brit) who did not inherit it - 10 male descendants affected |

| What did Francis Galton do? | - examined familial relationships of british hierarchy as well as famous pop-culture people - believed that many human traits are inherited and thus subjects to selection - concerned with "differential fertility" of the "genetically-inferior" |
| When were plants domesticated? | around 8,000 BCE |
| Who Was Wiliam Bateson? | - english biologist that expanded Mendel's conclusions to animals - coined GENETICS - Published Mendel's Principles of Heredity: a defency, with translation of Mendel's Hybridisation |
| Who was Democritus (in regards to genetics)? | - Nurture vs Plato's (nature) |
| What was the flaw with Darwin's The Origin of the Species ? | it was heavily criticized because there ws nothing regarding genetic mechanisms of variation and inheritance |
| Explain Pangenesis | - By Darwin - Cells of developing organisms can produce gemmules - Gemmules are carried by blood to reproductive organs where gametes are made - after fertilization, combined gemmules separate to different parts of the body to develop |
| Who was John C. Otto? | - provided first accurate account of hemophilia in modern medicla literature - followed a NH family of 'bleeders' - described the x-linked recesive inheritance of disorder |
| What is the Theory of Preformation? | the organism is contained in one of the sex cells as a fully developed homunculus - with proper nourishment the homunculus unfolds into adult proportions |
| What is Hemophilia? | - bleeding disorder mentioned in Talmud where circumcision was not reccomended due to large loss of blood where brothers, maternal uncles, and first cousins on MOTHER's side had the disorder |
| Who was Regnier de Graaf (in regards to genetics)? | - proposed that both sexes transmit agents of heredity - described small lamps in the ovaries and incorrectly thought he had discovered the mammalian egg -contributed greatly to the understanding of female mammalian reproductive system (ovulation) |
| What is the fixity of species? | says that living things retain the same form from the moment they appear on the earth |
| What was the main achievement of animal/plant domestication? | it allowed humans to transition from the hunter gatherer lifestyle to farm based living. Eventually, settlements and population expansion were on the rise |
| What is genetics? | the study of heredity in all its manifestations. specifically, genes are the main subject |
| The __________ is thought to be the location where domestication first occurred. But, what was learned later? | middle east, but domestication actually took place idependently in a number of places |
| Who was Carl von Linne (in regards to genetics)? | - developed a hierarchial system for classification of plants and animals - developed the binomial system of nomenclature - Fixity of species |
| Spermists belief | the homunculus was found in sperm |
| Who was Casper Wolff (in regards to genetics)? | - discredited the Theory of Preformationism (homunculus) - demonstrated that different adult structures of both animal and plants were not preformed but rather appeared gradually during the course of embryonic development |
| What is the Theory of Inheritance of Acquired Characteristics? | 2 major laws: 1. Change in the environment -> change in needs -> change in behavior -> excess use or disuse of organ or structure -> inc or dec in size of organ or structure 2. all changes of such are inherited - By JB Lamarck |
| Who was Aristotle (in regards to genetics)? | Developed theory of inheritance: - the male semen was only formed from the blood - the menstral blood contained the "matter" for offspring - the "form" controls and shapes the "matter" into the mature offspring |
| What is Germplasm? | 'discovered' by Weismann (not real) - heredity material that is set aside for reproductive purposes associated with the nucleus. There was a continuity of germplasm between generations |
| What is polydactyly? | - has bible mention - autosomal trait where one has multiple fingers and toes (usually 6) on each hand/foot - Pierre Louis Moreau de Maupertuis studied it in a Berlin family |
| Who coined the term Eugenics? | Francis Galton in 1883 |
| Who was William Harvey (in regards to genetics)? | - he proposed that all living things originate from an egg - introduced the theory of epigenesis |
| Who was Joseph Gottlied Kolreuter? | - first to perform systematic hybridization experiments in plants - studied the pollination process and revealed the important of insets to pollination |
| How long did it take for Mendel's work to be noticed? Who discovered it? | After 34 years, 3 botanists: 1) Hugo de Vries 2) Carl Correns 3) Erich con Tschermak all rediscovered Mendel's work |
| Why is genetics important? | 1. it unifies the study of biology 2. it has a profound impact on human affairs |
| Who was John Hay? | - studied a family of bleeders from MA - provided first detailed clinical manifestations of the disease - confirmed X-linked recessive nature - formulated first pedigree of the disease of Queen VIctoria |
| Who were the 2 big plant hydridists before Mendel? Why is Mendel known instead? | 1 Joseph Gottlied Kolreuter 2. Karl Friederich Gaertner - they obtained similar results to Mendel but failed to realize the significance |
| Who is Charles Darwin? | He contradicted Linnaean Fixity of the Species - 3 major claims: 1. variation is a characteristic of animals/plants 2. variation is inherited 3. organisms over-produce to survive 4. favorable variations are more likely to survive and pass down traits |
| Who said the following, "of the semen, however, I assert that it is secreted by the whole body healthy by healthy parts, sick by sick parts. Hence as a rule, bald-headed begets bald-headed, blue eyed beget blue-eyed" | Hippocrates |
