| Question | Answer |
|---|---|
| A complete haploid set of chromosomes of an organism. | Genome |
| Reproduction in which organisms develop from unfertilized ova. | Parthenogenesis |
| A chromosomal change that involves the addition or loss of entire genomes. | Euploidy |
| Any cell or organism that has multiple genomes. | Polyploid |
| Consists of three complete sets of chromosomes (genomes). | Triploid |
| A poison that disrupts the spindle fiber during cell dicision, resulting in polyploid cells. | Colchicine |
| Hacing four complete sets of chromosomes (genomes). | Tetraploid |
| An organism in which the chromosome number is not an exact multiple of the haploid number. | Aneuploid |
| The failure of a pair of homologous chromosomes to separate during meiosis. | Nondisjunction |
| An abnormal condition in which there are three chromosomes in a set instead of two. | Trisomy |
| A condition in which there is only one of a homologous chromosome pair. | Monosomy |
| A genetic disorder caused by a trisomy of the twenty-first chromosome. | Down Syndrome (trisomy 21) |
| A random change in a DNA molecule. | Mutation |
| Mutation that causes the death of the organism. | Lethal Mutation |
| The transfer of a chromosome segment to a nonhomologous chromosome; the movement of dissolved carbohydrates in plants. | Translocation |
| Mutation involving the loss of a segment of chromosome during replication; a mutation involving the loss of a nucleotide from a DNA chain. | Deletion |
| Chromosomal mutation in which genes break off a section of DNA and reattach but in the opposite order. | Inversion |
| A changing of the gene itself, which alters the sequence of nucleotide bases within a gene. | Gene Mutation |
| DNA mutation in which a nucleotide or nucleotides (other than three in number) are added to or taken from the chain so that subsequent codons are read incorrectly. | Frame Shift |
| The formation of living organisms from nonliving materials. | Spontaneous Mutation |
| A substance that induces mutation. | Mutagen |
| A mutation that affects only body cells (not gametes). | Somatic Mutation |
| A mutation that affects the gamete-producing cells. | Germ Mutation |
| A mechanism that prevents badly deformed or genetically defective persons from living and/or reproducing. | Genetic Screen |
| All the members of the same type of living things within an area. | Population |
| The sum of all of the alleles that every member of a species' population could possess at a given time. | Gene Pool |
| The differences between dfferent individual organisms of the sime kind; differences based on genotype; the expression of different individual characteristics in organisms of the same kind. | Variation |
| The method for selecting breeding stock in which only the desirable organisms are selected. | Mass Selection |
| The crossbreeding of two genetically unrelated individuals. | Hybridization |
| An increased capacity for growth or strength in a hybrid. | Heterosis |
| The mating of closely related organisms. | Inbreeding |
| An organism that is homozygous for certain traits. | Pure Strain |
| The science that deals with improvement of the uman race by applying principles of genetics. | Eugenics |
| Medical and nonmedical methods used to find information on a person's genetic makeup. | Genetic Screening |
| A fiberoptic device that can be inserted into the womb to take pictures of the unborn child. | Fetoscope |
| Medical test using amniotic flued to determinethe sex and health of an unborn child, including possible genetic defects. | Amniocentesis |
| The mechanical placement of sperm into a female's reproductive organs. | Artificial Insemination |
| The man who supplies the sperm for the zygote of a child. | Biological Father |
| The union of sperm and egg in an artificial setting, usually in a laboratory. | In Vitro Fertilization |
| The woman who supplies the ovum for the zygote of a child. | Biological Mother |
| A woman who nurtures and brings to birth from her womb a child for which she did not provide the ovum. | Surrogate Mother |
