Step I: Standardized Test Item

In 1994, a new tomato variety that ripens slowly

was developed by a laboratory technique that

did not involve methods of natural reproduction.

This new variety contains a section of a DNA

molecule not found in the tomato from which it

was originally developed. Which technique was

most likely used to develop this new variety of

tomato?

1 amniocentesis


3 genetic engineering

2 cross
-
pollination


4 karyotyping

Step I: Test Item Structure


1. For a Multiple Choice Test Item:


Stem: Describes the production of a new species of
tomato and asks what method was used for the
development of this tomato.


Diagram: None for this question.

²
Distractors: 1,2,4. Genetic terms, but not
appropriate.

²
Correct answer choice: 3. Genetic engineering

²
What makes this the correct choice?: This is the
only choice where human intervention in the
genes of the tomato is possible.

Students will be able to deduce that the processes
involved in the description of the development of the
new variety of tomato in the question point to
genetic manipulation through genetic engineering.
