Provides definitions of polyploidy, nondisjunction, tetraploid/autopolyploid, visual diagrams of autopolyploidy and allopolyploidy speciation, visual of a normally functioning cell, and a worked through example with ploidy levels.

Where are substitutions more common? - ANSWERSat positions that do not change the amino acid What does neutral mean? - ANSWERSdon't convey a selective advantage or disadvantage What does the molecular clock do? - ANSWERShelps you calculate how long it has been since two species "diverged" from a common ancestor What is positive directional selection? - ANSWERSrate of non-synonymous substitution exceeds the rate of synonymous substitution What is neutral selection? - ANSWERSr...

Biology 1108 Exam 3 1. An important result from the monohybrid cross experiments was that phenotypes appeared in predictable ratios, indicating that only one copy of each gene passes from a parent to its offspring. This is now referred to as: a. Sympatric speciation b. The Hardy-Weinberg Equilibrium c. The Law of Independent Assortment d. The Law of Segregation e. The Theory of Natural Selection 2. In Mendel's crosses, he found that it was possible to recover traits that were present i...

Two populations of crickets have stopped interbreeding over time, although they reside in the same geographic region. What is one possible explanation? Question 1 options: They have experienced reinforcement because of reconnection at a hybrid zone. They have developed a temporal isolation, a kind of prezygotic barrier. Autopolyploidy has occurred, and the species are separated by a sympatric barrier. Save Question 2 (5 points) "Survival of the fittest," or the reproductive advantage i...
