What is the reason that closely linked genes are typically inherited together? - ANSWER The likelihood of a crossover event between these two genes is low All female mammals have one active X chromosome per cell instead of two. What causes this? - ANSWER Activation of the XIST gene on the X chromosome that will become the Barr body In his transformation experiments, what did Griffith observe? - ANSWER Mixing a heat-killing pathogenic strain of bacteria with a living nonpathogenic strain ca...
