The expression of a trait; what you see.

refers to the genetic makeup of an individual

An organism that has the same genes for a trait (ex. TT or tt)

the passing of traits from parent to offspring

Principle stating pairs of genes in the parent cell separate when gametes are formed and occurs during anaphase I of meiosis

Principle of Independent Assortment

A farmer is considering the advantages of cloning a herd of cattle from a single cow. What is one advantage of a cloned herd?

All cattle in the herd would have the most desired traits.

All cattle in the herd would have more genetic variation.

All cattle in the herd would have more resistance to diseases.

All cattle in the herd would have much longer life spans.

Scientists have produced a genetically modified orange tree that is resistant to disease. Which of the following is the best example of a potential benefit to society that could result from this biotechnology?

increase in orange crops produced

reduction in orange crops produced

increase in the cost of orange crop

a change in the distribution of insects that pollinate orange flowers

Many species of bacteria have become resistant to antibiotics because antibiotics have been so widely used. Now, bacteria that used to be killed by antibiotics are more difficult to treat. What is the best way to proceed in dealing with this public health problem?

Antibiotics should only be prescribed to people with bacterial infections

Antibiotics should no longer be used.

Antibiotics should be made available to anyone without a prescription.

Anti-viral medications should now be used instead of antibiotics.

What is selective breeding?

Mating and producing offspring of animals or plants for specific traits (artificial selection)

Using biotechnology techniques to solve environmental issues

An application of using DNA technology to help environmental scientists would be ___.

make transgenic bacteria that can be used to clean up oil spills more quickly than do the natural bacteria

use PCR to analyze DNA at a crime scene

create a tobacco plant that glows in the dark

clone the gene for human growth hormone to treat pituitary dwarfism

This technique used to analyze DNA involves the

separation of DNA fragments based on size AND charge

synthesis of new DNA strands from subunits

production of genetically engineered DNA molecules

removal of defective genes from DNA

Why do the fragments of DNA in gel electrophoresis travel away from the negative electrode?

DNA is negatively charged so attracted to the positive end of the unit

DNA is positively charged to attracted to the negative end of the unit

the agarose gel in negatively charged

the agarose gel is positively charged

In gel electrophoresis, the largest DNA fragment will appear

farthest from the starting wells

three quarters away from the starting wells

it depends on how many fragments there are

What do half colored symbols represent?

The individual is a carrier (heterozygous).

The individual expresses the trait.

The individual has both recessive alleles.

The individual has both dominant alleles.
