lab 12

Question 1

genetic change in population

Answer 1

evolution

Question 2

permanent alteraion of base sequence in a cells DNA

Answer 2

mutation

Question 3

occurs when genetic material moves from one population to another

Answer 3

gene flow

Question 4

occurs when individuals in a population choose mates on the basis of phenotype and genotype

Answer 4

non-random mating

Question 5

effect of random events on allele and genotype frequencies and has an effect inverse to population size.

Answer 5

genetic drift

Question 6

increased survival and reproduction of one phenotype over others in a population

Answer 6

selection

Question 7

small changes in population

Answer 7

microevolution

Question 8

occurs when seperate populations evolve independently of each other eventually resulting in enough differences that the seperate populations are no longer able to interbreed

Answer 8

speciation

Question 9

large scale change to population

Answer 9

macroevolution

Question 10

5 conditions

Answer 10

1. no mutation
2. no gene flow
3. random mating
4. large population size
5. no selection

Question 11

selection when one phenotype survives and reproduces better than another

Answer 11

fitness

Question 12

three types of selection

Answer 12

natural, artificial, and sexual

Question 13

effect of random events on allele and genotype frequencies

Answer 13

genetic drift

Question 14

occurs when a population is reduced to an extremely small size

Answer 14

population bottleneck
