Document Summary
Looking ahead: cell figure 163-792: the segregation of old histones directs chromosome segregation & cell fate, they align and go towards the centrosome. Gregor mendel (1822-1884: key plant breading experiment conducted in 1856 to 1863, published in 1866, rediscovered in the 1900s by hugo de vries. Benefits of his experimental system: his peas were highly in-bred (this is the key to his success, they were basically self-fertilizing plants thus breading true . Ex: when two tall plants bred, they produced tall plants. His experiments were designed so he could study one trait at a time. In a genetic cross, the parents are referred to as p (parental generation) Their offspring are known as f1 then f2. Ex: tall and dwarf plants for every dwarf there are three tall ones. (view lecture slide) All of his traits behaved the same way they seemed to be controlled by a heritable factor that came in one of the following forms.
