Genetically Modified Foods The creation of transgenic crop plants using recombinant DNA methods involves the transfer of just one gene or a small number of genes to the plants, in contrast to classical breeding methods in which hundreds or even thousands of genes are transferred at once. Explain why this is true. If fewer genes are transferred during the creation of transgenic crops, why are some people afraid that they are dangerous?

The creation of transgenic crop plants using recombinant DNA methods involves the transfer of just one gene or a small number of genes to the plants, in contrast to classical breeding methods in which hundreds or even thousands of genes are transferred at once. Explain why this is true. If fewer genes are transferred during the creation of transgenic crops, why are some people afraid that they are dangerous?

Summary Introduction

To determine: The reason for the truthfulness of the fact that relatively lower numbers of genes are transferred in the RDT as compared to typical breeding procedures.

Introduction: In classical breeding techniques, transfer of hundreds to thousands of genes takes place to develop transgenic crops. These days, however, methods of biotechnology such as recombinant DNA techniques are used to develop transgenic plants which have increased yield and resistance towards various pests and herbicides. These new methods involve transfer of a very small number of genes to develop transgenic plants.

Explanation of Solution

In classical breeding techniques transgenic crops were not specifically developed to provide them resistance towards certain pests or diseases. These transgenic crops were developed through artificial selection. In the method of artificial selection, crops with desired traits are artificially selected and then bred with the crops possessing other desired traits. Thus, thousands of genes are transferred to produce transgenic crops...

Summary Introduction

To determine: The reason which makes some people afraid that the transgenic crops are dangerous despite the transfer of fewer genes for their creation.
