1. What is the definition of transgenic?

The use of GMOs in agriculture industry.

The use of plants to make products of use to people.

Recombinant DNA molecule.

Organisms that have been engineered to express a gene from
another species.

2. A wild type allele ...

is a mutant, non-functional allele.

is only expressed in the presence of lactose.

is the most favorable allele in the population.

is the allele with the highest level of functional protein.

is the allele that is the most common in the population.

3. If an organism has a genotype that includes a dominant allele for a trait, what
can be inferred about its phenotype?

The phenotype will only express recessive traits.

The phenotype will not express any traits.

The phenotype will likely express the dominant trait.

The phenotype will be a mix of dominant and recessive traits.

4. Which of the following best defines a phenotype in the context of genetics?

, The traits that are exclusively determined by an organism's
environment.

The specific genes an organism inherits.

The observable characteristics resulting from an organism's genes
and environmental influences.

The entire genetic code of an organism.

5. What term is used to describe the specific alleles an organism has for a given
trait?

Trait

Allele

Phenotype

Genotype

6. If a new organism is discovered that does not conform to the principles of
Cell Theory, what implications would this have for our understanding of life?

It would challenge the current understanding of what constitutes a
living organism and may lead to a reevaluation of the definitions of
life and cellular organization.

It would suggest that life can exist without cells, which would not
affect current biological theories.

It would confirm that all life is composed of cells and reinforce
existing theories.

It would imply that cells are not necessary for life, leading to the
conclusion that viruses are living organisms.
