Activity Procedure
In this activity you will observe, record, and interpret data related to genetics. Specifically, in the first four procedures you will investigate the offspring that can be produced from different sets of parent bugs. In the last three procedures you will investigate how the composition a small bug population can change over time when there is (or isn’t) a breeding preference.
Procedure I ? Part A ? Baby bugs produced when the parents are BB and bb
Adult bugs breed to produce offspring. Only a single data run is needed for this procedure.
- select the Baby Bugs testing setup by clicking or tapping on its button
- select the bug parents by clicking on the BB & bb button
- start the data run by clicking or tapping on the Start Data Run button
Note: allow 6 seconds for the data run to complete ? do not interrupt the data run - record your Bug Baby Results in the Procedure I ? Part A Data Table of your Activity Form
- take a screenshot of this completed data run (it will be used to confirm your identity and Activity Data Code)
- press the reset button and move on to the next procedure
Analysis of Procedure I ? Part A Data
Complete the Procedure I ? Part A section of your Activity Form. Review the background material as needed.
Procedure I ? Part B ? Baby bugs produced when the parents are BB and Bb
Adult bugs breed to produce offspring. Note: 10 data runs are required for this procedure.
- select the Baby Bugs testing setup by clicking or tapping on its button
- select the bug parents by clicking on the BB & Bb button
- start the data run by clicking or tapping on the Start Data Run button
Note: allow 6 seconds for the data run to complete ? do not interrupt the data run - record your Bug Baby Results in the Procedure I ? Part B Data Table of your Activity Form
- press the reset button and do your next data run or, if all 10 data runs completed, move on to the next procedure
Analysis of Procedure I ? Part B Data
Complete the Procedure I ? Part B section of your Activity Form. Review the background material as needed.
Procedure I ? Part C ? Baby bugs produced when the parents are bb and Bb
Adult bugs breed to produce offspring. Note: 10 data runs are required for this procedure.
- select the Baby Bugs testing setup by clicking or tapping on its button
- select the bug parents by clicking on the bb & Bb button
- start the data run by clicking or tapping on the Start Data Run button
Note: allow 6 seconds for the data run to complete ? do not interrupt the data run - record your Bug Baby Results in the Procedure I ? Part C Data Table of your Activity Form
- press the reset button and do your next data run or, if all 10 data runs completed, move on to the next procedure
Analysis of Procedure I ? Part C Data
Complete the Procedure I ? Part C section of your Activity Form. Review the background material as needed.
Procedure I ? Part D ? Baby bugs produced when the parents are Bb and Bb
Adult bugs breed to produce offspring. Note: 10 data runs are required for this procedure.
- select the Baby Bugs testing setup by clicking or tapping on its button
- select the bug parents by clicking on the Bb & Bb button
- start the data run by clicking or tapping on the Start Data Run button
Note: allow 6 seconds for the data run to complete ? do not interrupt the data run - record your Bug Baby Results in the Procedure I ? Part D Data Table of your Activity Form
- press the reset button and do your next data run or, if all 10 data runs completed, move on to the next procedure
Analysis of Procedure I ? Part D Data
Complete the Procedure I ? Part D section of your Activity Form. Review the background material as needed.
Procedure II ? Part A ? Changes in bug population over time when there is a breeding preference for blue-rimmed bugs
This is a situation where natural selection occurs, specifically, sexual selection based on a trait.
A small population of bugs live, potentially breed, and die. Bug interactions, births, and deaths are random. For this procedure there is a strong breeding preference for blue-rimmed bugs. Only a single data run is needed for this procedure.
- select the Bug Pop testing setup by clicking or tapping on its button
- select the Blue trait breeding preference by clicking on its button
- start the data run by clicking or tapping on the Start Data Run button
Note: allow 300 seconds (5 min) for the data run to complete ? do not interrupt the data run - record your Bug Population results in the Procedure II ? Part A Data Table of your Activity Form
- press the reset button and move on to the next procedure
Analysis of Procedure II ? Part A Data
Complete the Procedure II ? Part A section of your Activity Form. Review the background material as needed.
Procedure II ? Part B ? Changes in bug population over time when there is a breeding preference for yellow-rimmed bugs
This is a situation where natural selection occurs, specifically, sexual selection based on a trait.
A small population of bugs live, potentially breed, and die. Bug interactions, births, and deaths are random. For this procedure there is a strong breeding preference for yellow-rimmed bugs. Only a single data run is needed for this procedure.
- select the Bug Pop testing setup by clicking or tapping on its button
- select the Yellow trait breeding preference by clicking on its button
- start the data run by clicking or tapping on the Start Data Run button
Note: allow 300 seconds (5 min) for the data run to complete ? do not interrupt the data run - record your Bug Population results in the Procedure II ? Part B Data Table of your Activity Form
- press the reset button and move on to the next procedure
Analysis of Procedure II ? Part B Data
Complete the Procedure II ? Part B section of your Activity Form. Review the background material as needed.
Procedure II ? Part C ? Changes in bug population over time when there is not a rim-color breeding preference
In this situation genetic drift determines the outcome. You may be expected to share and compare your results with your classmates. Your instructor will provide details as needed.
A small population of bugs live, potentially breed, and die. Bug interactions, births, and deaths are random. For this procedure there is not a rim-color breeding preference among bugs. Only a single data run is needed for this procedure.
- select the Bug Pop testing setup by clicking or tapping on its button
- select the None trait breeding preference by clicking on its button
- start the data run by clicking or tapping on the Start Data Run button
Note: allow 300 seconds (5 min) for the data run to complete ? do not interrupt the data run - record your Bug Population results in the Procedure II ? Part C Data Table of your Activity Form
- press the reset button and move on to the next procedure
Analysis of Procedure II ? Part C Data
Complete the Procedure II ? Part C section of your Activity Form. Review the background material as needed.
Post-Activity
Complete any remaining questions. To help with the questions, review the background material, your data, and any additional materials suggested by your instructor.
