Which of the following is true about selective breeding and genetically modified organisms?
a. farmers have been able to produced new varieties of crops by selective breeding alone. b. vitamin a genes have been introduced into rice to make these crops resistant to herbicides. c. desired traits engineered into crops must come from dna of the same species (e. g. rice genes must always be used to genetically engineer rice).d. vitamin a genes have been introduced into rice to make these crops resistant to pests. e. gmos are always superior to selectively bred organis.

A. Farmers have been able to produced new varieties of crops by selective breeding alone.✔

B. Vitamin A genes have been introduced into rice to make these crops resistant to herbicides.❌

C. Desired traits engineered into crops must come from DNA of the same species (e.g. rice genes must always be used to genetically engineer rice).❌

D. Vitamin A genes have been introduced into rice to make these crops resistant to pests.❌

E. GMOs are always superior to selectively bred organis.

Explanation:

Selective breeding can preferablly be called artificial selection.

It's used to produced new varieties of crops with desirable characteristics or traits. In this case, two parents with the desired phenotypic traits is reproduced to yield offspring with those new traits.

E.g. wheat plants that produce lots of grain and another wheat plant that is resistant to a particular disease or infective pest can be selectively breaded to produce crops with both desired traits.
