front 1 What is a transgenic organism? | back 1 An organism that has incorporated a piece of foreign DNA, meaning from a different organism that was artificially introduced. |
front 2 What are some differences between natural selection and selective breeding? | back 2 It arises from random mutations that can be beneficial or deleterious based on the environment |
front 3 What is beneficial mutations? | back 3 They will increase in frequency in the population due to an increase in their likelihood to be passed down. |
front 4 Will deleterious mutations be passed down? | back 4 no |
front 5 Selective breeding can also be called what? | back 5 Artificial selection |
front 6 What is selective breeding? | back 6 Occurs when humans intervene and naturally breed together different organisms to get a desirable trait. |
front 7 What is this... On a warm island, a species of bird has thin feathers. Occasionally, a few birds are born with a mutation for thick feathers. After a random cold snap, the next year there are far more birds being born with thick feathers. | back 7 natural selection |
front 8 What is this... A farmer breeds a tall wheat stalk with one with a high yield to get tall, high yield wheat. | back 8 selective breeding |
front 9 What is this... The whale population in the arctic took a large decline due to overhunting. The resulting gene pool had different allele frequencies than before. | back 9 Genetic bottleneck |
front 10 What is this... 4 lizards from a group of 30 got separated and started their own lizard colony with a distinct gene pool. | back 10 founder effect |
front 11 Gel Electrophoresis separates DNA fragments by______ with the__________ fragments traveling the furthest through the gel. | back 11 size, smallest |
front 12 True or false translocation can NOT be caused by a Single Nucleotide Polymorphism? | back 12 true |
front 13 Which of the following are ways to bring about adaptations? | back 13 Natural selection |
front 14 What is meant by a conserved sequence? | back 14 This is a sequence that is fairly standard across multiple species and over time! It does not have a high mutation or deviation rate |
front 15 When comparing homology, should scientists compare the nucleotide or amino acid sequences of two organisms? Why? | back 15 Amino acid codes are degenerate, meaning that even if a nucleotide was mutated and changed, it may still code for the same amino acid. Amino acid codes take longer to deviate than nucleotide ones. |
front 16 Meiosis can occur in triploid cells | back 16 false |
front 17 In mitosis, a haploid cell starts G1 with 8 chromosomes. How many will it have at S phase, anaphase, and telophase? | back 17 S phase - 8 anaphase - 16 telophase -16 |
front 18 Microtubules connect to DNA in prometaphase | back 18 false |
front 19 In mitosis, chromosome number doubles in_____while DNA amount doubles in________ | back 19 anaphase, s phase |
front 20 Sister chromatids separate in anaphase 1 of meiosis | back 20 false |
front 21 A diploid organism that starts G1 of meiosis with 46 chromosomes will have how many chromosomes at the end of Meiosis 1? | back 21 23 |
front 22 A diploid organism that starts G1 of meiosis with 46 chromosomes will have how many chromosomes at the end of Meiosis 2? | back 22 23 |
front 23 A diploid organism that starts G1 of meiosis with 46 chromosomes will have how many chromatids at the end of S phase? | back 23 92 |
front 24 A diploid organism that starts G1 of meiosis with 46 chromosomes will have how many chromatids at the end of Meiosis 1? | back 24 46 |
front 25 Prior to meiosis, a cell has the genotype AaBbCc. What is the predicted frequency of the gamete ABC? | back 25 12.5 (1/8) |
front 26 What best describes a change in allele frequencies due to genes moving from one population to another? | back 26 gene flow/migration |
front 27 Which organelles carry genetic material that can be inherited by daughter cells during mitosis? | back 27 nucleus, mitochondria, and chloroplast |
front 28 If you measure the percentage of adenine in yeast to be 31.3%, what is the approximate amount of cytosine you would expect to observe? | back 28 18.7% |
front 29 Kevin is arguing with Lillie about model organisms. Kevin believes that ducks should be considered model organisms because their generation time is only a few weeks, they have 100,000 offspring each time, they are very inexpensive to house, and they are relatively adaptable to the lab setting. Using what you know about model organisms, is Kevin correct? | back 29 No, 100,000 offspring is not a manageable number of offspring |
front 30 You are cramming for your test and cannot remember her model organisms. You can only remember 5 of them and are left with 4 options for the last one. Which of the below options is one of the model organisms? | back 30 Escherichia coli |
front 31 Manx cats, when heterozygous, have a shortened or missing tail. Brianna decided to cross two carriers of this mutation and is surprised when two thirds of their offspring have shortened or missing tails, and only one third are normal. What could be attributed to this phenomenon? | back 31 The allele that causes the mutation is a recessive lethal allele. |
front 32 If you crossed two heterozygous plants, how many of the offspring will also be heterozygous? | back 32 1/2 |
front 33 How many Barr Bodies would an XXY individual produce? | back 33 1 |
front 34 What did Thomas Hunt Morgan discover? | back 34 Chromosome theory of inheritance |
front 35 What did Linus Pauling discover? | back 35 Gel electrophoresis |
front 36 What did Sutton and Boveri discover? | back 36 chromosomes in meiosis mirror hereditary transmission of genes |
front 37 What did mary lyon discover? | back 37 random x inactivation |
front 38 What did murray barr discover? | back 38 barr bodies |
