Use the following information to answer the question. A plantlike organism on the hypothetical planet Pandora has three genetic traits: leaf color, controlled by gene L; a stem texture, controlled by gene S; and root length controlled by gene R. The three genes are linked and recombine. A geneticist performed a testcross with a strain of the organism that is heterozygous for the three traits. She recorded progeny with the following phenotypic distribution: Phenotypes Leaves Stems Roots Number 1 l S R 14 2 l S r 0 3 l s R 32 4 l s r 440 5 L s R 0 6 L s r 16 7 L S r 28 8 L S R 470 Total 1,000 What is the approximate distance between genes L and S

Go Direct Force and Acceleration couples a 3-axis accelerometer with a stable and accurate force sensor that measures forces as small as ±0.1 N and up to ±50 N.

Bluetooth Connection

USB Connection

Install Graphical Analysis 4 on your computer, Chromebook™, or mobile device. See www.vernier.com/ga4 for software availability.

Charge your sensor for at least 2 hours before first use.

Turn on your sensor by pressing the power button once. The Bluetooth® LED will blink red.

Launch Graphical Analysis 4.

Click or tap Sensor Data Collection.

Click or tap your Go Direct sensor from the list of Discovered Wireless Devices. Your sensor's ID is located near the barcode on the sensor. The Bluetooth LED will blink green when it is successfully connected.

This is a multi-channel sensor. The active channel is listed in the Connected Devices Sensor Channels list. To change channels, select the check box next to the Sensor Channel(s) you would like to activate.

Click or tap Done to enter data‑collection mode.

If using a computer or Chromebook, install Graphical Analysis 4. If using LabQuest 2, make sure LabQuest App is up to date. See www.vernier.com/ga4 for Graphical Analysis 4 availability or www.vernier.com/downloads to update LabQuest App.

Connect the sensor to the USB port.

Launch Graphical Analysis 4 or turn on LabQuest 2. You are now ready to collect data.

This is a multi-channel sensor. To change the default channel selections, see www.vernier.com/start/gdx-for

Charging the Sensor

Connect Go Direct Force and Acceleration to the included Micro USB Cable and any USB device for two hours.

You can also charge up to eight Go Direct Force and Acceleration Sensors using our Go Direct Charge Station, sold separately (order code: GDX-CRG). An LED on each Go Direct Force and Acceleration indicates charging status.
