Genetic Terms Quiz

What is the definition of a species in genetic terms?

• A group of similar organisms that can breed and produce fertile offspring.

• The total number of genes in a population.

• A type of genetic mutation.

• The transfer of genetic material from one organism to another that is not its offspring.

What does the term 'gene pool' refer to?

• The physical appearance of an organism.

• The total number of genes in a population.

• A type of genetic mutation.

• The transfer of genetic material from one organism to another that is not its offspring.

How is allele frequency related to evolution?

• It is the rate at which new species are formed.

• It is the total number of genes in a population.

• It refers to how often a particular allele occurs in a gene pool.

• It is the transfer of genetic material from one organism to another that is not its offspring.

What is the difference between genotype and phenotype?

• Genotype refers to the genetic makeup, while phenotype refers to the physical appearance.

• Genotype is the total number of genes in a population, while phenotype is the rate at which new species are formed.

• Genotype is a type of genetic mutation, while phenotype is the transfer of genetic material.

• Genotype is the transfer of genetic material from one organism to another that is not its offspring, while phenotype is the physical appearance.

Which process contributes to genetic variation by combining genes from two parents?

• Mutation

• Genetic Recombination during Sex

• Lateral Gene Transfer

• Single-gene Traits

What is lateral gene transfer?

• The process where organisms pass genes from one individual to another that is not its offspring.

• The total number of genes in a population.

• A type of genetic mutation.

• The physical appearance of an organism.

What is the difference between single-gene traits and polygenic traits?

• Single-gene traits are controlled by one gene, while polygenic traits are controlled by two or more genes.

• Single-gene traits are controlled by two or more genes, while polygenic traits are controlled by one gene.

• Single-gene traits refer to the total number of genes in a population, while polygenic traits refer to the rate at which new species are formed.

• Single-gene traits are a type of genetic mutation, while polygenic traits are the transfer of genetic material.

How is evolution defined in genetic terms according to the key question in the lesson summary?

• The transfer of genetic material from one organism to another that is not its offspring.

• The rate at which new species are formed.

• The change in allele frequency over time within a population.

• The total number of genes in a population.

What is the genetic definition of a species?

• A group of organisms that are physically similar and able to interbreed, but do not mate with other groups.

• A group of organisms that share the same habitat.

• A group of individuals that are physically different and cannot interbreed.

• A group of individuals of the same species that mate and produce offspring.

What does the gene pool of a population consist of?

• All genes within a group's members, including all different alleles for each gene.

• Only the dominant alleles for each gene within the group's members.

• The most common alleles found in the environment.

• The single-gene traits controlled by one gene.
