Genetics Quizs

Mitosis

• A process that occurs in the cytoplasm of a cell and results in the formation of two identical daughter cells.

• A process that takes place in the nucleus of a dividing cell, involves a series of steps, and results in the formation of two new nuclei each having the same number of chromosomes as the parent nucleus.

• A method of asexual reproduction in unicellular organisms that does not involve cell division.

• A process that occurs during the synthesis phase of the cell cycle and leads to the duplication of DNA.

Karyotype

• A display of the chromosome pairs of a cell arranged by size and shape.

• A type of genetic mutation that affects chromosome structure.

• A method used to sequence DNA in a laboratory.

• A technique for cloning organisms from a single cell.

Pedigree

• A type of genetic mutation that occurs in a single generation.

• A diagram of a family tree showing the occurrence of heritable characteristics in parents and offspring over multiple generations.

• A method for cloning organisms in a laboratory setting.

• A visual representation of the evolutionary relationships among species.

Sex Chromosome

• A type of chromosome that determines the physical traits of an individual.

• One of the pair of chromosomes responsible for determining the sex of an individual.

• A chromosome that carries genetic information unrelated to sex.

• A chromosome that is only found in males.

Mutation

• A common change in the genetic material that has no effect on diversity.

• A rare change in the genetic material, ultimately creating genetic diversity.

• A process that eliminates genetic variations in a population.

• A method of cloning genes for agricultural purposes.

Autosome

• A chromosome that is not directly involved in determining sex, as opposed to a sex chromosome.

• A chromosome that determines the sex of an individual.

• A type of chromosome that only exists in males.

• A chromosome that is involved in the immune response.

Chromosome

• Any of the usually linear bodies in the cell nucleus that contain the genetic material.

• Small, circular DNA molecules found in bacteria.

• Structures that help in the synthesis of proteins in the cell.

• Cellular structures responsible for energy production.

Homologous Chromosomes

• Chromosomes that are identical in size and shape.

• Chromosomes having the same or allelic genes with genetic loci usually arranged in the same order.

• Chromosomes that are formed during cell division.

• Chromosomes that contain only one type of gene.

Phenotype

• The genetic makeup of an organism.

• The observable properties of an organism that are produced by the interaction of the genotype and the environment.

• The process by which organisms adapt to their environment.

• The study of heredity and the variation of inherited characteristics.

Dominant Trait

• A genetic trait is considered dominant if it is expressed in a person who has only one copy of the gene associated with the trait.

• A genetic trait is considered dominant if it requires two copies of the gene to be expressed.

• A genetic trait is considered dominant if it is only expressed in males.

• A genetic trait is considered dominant if it is always expressed regardless of other genes present.
