BIOL 210 Genetics Module 1 Questions & Answers 2026 |
Latest Study Guide
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.
,7. Describe how a phenotype is influenced by both genotype and
environmental factors.
A phenotype is unrelated to genetic or environmental factors.
A phenotype is only influenced by environmental factors.
A phenotype results from the interaction between an organism's
genotype and its environment.
A phenotype is solely determined by the genetic makeup of an
organism.
8. If a geneticist discovers a new gene associated with a specific trait, how
would the Law of Inheritance apply to the study of this gene?
It would indicate that the gene has no effect on inheritance.
It would help predict how the trait associated with the gene is
inherited in future generations.
It would suggest that the trait can only be expressed in certain
environments.
It would mean that the gene is irrelevant to the study of inheritance.
9. The selective breeding of animals and plants by humans is also known as
selection.
stabilizing
artificial
natural
disruptive
sexual
, 10. What is the primary function of vectors in genetic engineering?
To replicate DNA within a cell
To degrade unwanted DNA
To insert DNA fragments into host organisms
To synthesize proteins from DNA
11. What are the three main principles of Cell Theory?
All cells contain DNA and RNA.
Cells can arise spontaneously from non-living matter.
All living things are composed of cells, cells are the basic units of
structure and function, and new cells arise from existing cells.
Cells are the smallest units of life and cannot be divided further.
12. What is inheritance
A very small version of evolution
Getting a grandfather clock from your grandfather
Genes that get passed down through parents
Recessive genes passed down through parents that mutate
13. If a human cell undergoes meiosis, how would the number of homologous
chromosome pairs change in the resulting gametes?
The number of homologous chromosome pairs would be reduced to
0 pairs in each gamete.
The number of homologous chromosome pairs would remain the
same at 22 pairs in each gamete.
