BIO 182 Exam 2 Questions And Answers 100% How many modes of selection are there? 3 What are the modes of selection? Stabilizing selection, directional selection, and disruptive selection Stabilizing Selection The mean of the trait remains similar over time but the standard deviation decreases Directional Selection The mean phenotype shifts in a particular direction Disruptive Selection The standard deviation of the trait increases as individuals with the mean value disappear. Stabil...

A thin-shelled crab can more readily move to escape a predator than can a thick-shelled crab, but it is more vulnerable to predators that drill through the shell. Because of these opposing forces, shell thickness for many types of crabs has remained within a narrow range over a long time. This would be an example of _____________________________ selection correct answer: stabilizing What is genetic change in a population over time? correct answer: evolution What is the mode of natural...

Convergent vs Divergent Evolution - ANSWER -Divergent: one broad class but because of different features they diverge -Convergent: similar features between 2 different classes Punctuated Equilibrium vs Gradualism - ANSWER -Punctuated: concrete & defined phenotypes -Gradualism: phenotypes gradually evolve Speciation - ANSWER Formation of new species 1) Allopatric: separated by geographical barrier (mountain, ocean, river) -Barrier divides species 1 and species 2 2) Parapatric...

Reasons why Mendel used pea plants Correct Answer-Hermaphrodites (can self fertilize & cross easily) and discrete phenotypes Fundamental thing Mendel did Correct Answer-Count, allowing for systemization True Breeding Strain Correct Answer-produces own phenotype Mendel's Law of Segregation Correct Answer-1. One gene controls traits 2. 2 forms of a gene 3. Each individual has 2 alleles 4. Each parent contributes 1 allele 5. One allele is dominant to the other 6. Alleles separate equ...
