Unit 2, Concept 2.2 Influencing Inheritance Study Guide
Isolate genes for these desired traits from any organism known to have them, and then use transgenesis to insert the genes into the corn genome.
A scientist wants to develop a fast-growing, pest-resistant, nutrient-rich variety of corn. What would be the fastest, most effective method for achieving this goal?
True of genetic mutations
Genetic mutations are inheritable material that could be beneficial or deleterious to an organism.
creating trees with more leaves
How could selective breeding be used to reduce deforestation?
increased agricultural productivity
Is a benefit of transgenic plants
Some; Other
The characteristics of an organism can best be described as follows:_______________ traits are inherited, and _______________ traits result from interactions with the environment.
A farmer takes pollen from a plant with desired traits and intentionally places the pollen on a plant with other desired traits.
Which of the following is an example of genetic engineering?
Humans change the DNA of of algae so the organism will produce ethanol.
Which of the following is an example of genetic engineering?
Fruit that softens more slowly.
Which of the following traits could most likely be developed through selective breeding of tomato plants?
using cloning to increase the population of endangered species and preserve their genomes.
Which of the following would be a plausible method for using genetic engineering to conserve endangered species?
Gene therapy can replace or remove faulty or damaged genes.
Which statement is true of gene therapy?
Cross-pollination could pass herbicide-resistant genes to weeds.
Why are people concerned that transgenic plants may lead to an increase in the use of herbicides?
Trait
a characteristic or property of an organism
Characteristic
a feature of an organism; something you can observe about an organism
Offspring
a new organism that is the product of reproduction
Endangered Species
a species that is in danger of extinction due to its low number of remaining individuals
DNA
found in the nucleus of a cell, a long nucleic acid molecule containing the genetic instructions for the development and functioning of all living organisms
Genetic Engineering
process where foreign or modified genes are directly incorporated into an organism's genome
Artificial Selection
selective breeding of plants and animals by humans
Bacteria
single-celled organisms without an organized nucleus
Gene
the basic unit of heredity in a living organism; a segment of DNA or RNA
