evolution

Question 1

evolution

Answer 1

the process by which the characteristics of populations change over time. It also gives rise to new species.

Question 2

artificial selection

Answer 2

humans interfere in traits in plants and animals and the steps taken to enhance and perpetuate these traits in future generations

Question 3

natural selection

Answer 3

individuals w/ certain heritable traits survive and reproduce at a higher rate than others

Question 4

conditions of natural selection

Answer 4

mutation, gene flow, genetic drift, natural selection?

Question 5

how might resistance to a chemical/drug develop?

Answer 5

elements such as transposing can transfer from a plasmid to other plasmids or from a DNA chromosome to plasmid and vice versa that cause the transmission of antibiotic resistance genes in bacteria

Question 6

what do different beaks tell us about different species?

Answer 6

certain beak shapes/sizes on certain islands give a survival advantage.

Question 7

hardy-weinburg

Answer 7

the presence of genetic variation does not guarantee evolution of a population

Question 8

hardy-weinburg conditions

Answer 8

• mutations
• gene flow
• random mating
• natural selection
• large population size

Question 9

founder efffect

Answer 9

a few individuals from a population start a new population w/ a different allele frequency than a original population. random, non adaptive

Question 10

bottleneck effect

Answer 10

• suddenly change in environment
• drastic reduction in population size
• survivors gene pool does not reflect the original population variation
• random and non adaptive

Question 11

anoles as convergent evolution

Answer 11

• case of where different living things independently acquire the same adaptations to the same challenges
• short legged, long legged, dewlap colors?
• females might not mate w/ different color dewlap males
