| deoxyribonucleic acid, the material that contains the information that determines inherited characteristics | ||
| threadlike structure within the nucleus containing the genetic information that is passed from one generation of cells to the next | ||
| one of a number of different forms of a gene | ||
| sequence of DNA that codes for a protein and thus determines a trait | ||
| Similarly constructed chromosomes that have the same shape and contain genes for the same traits | ||
| the regular sequence of growth and division that cells undergo | ||
| cell division in which the nucleus divides into nuclei containing the same number of chromosomes | ||
| first phase of mitosis in which chromosomes become visible and nuclear membraine disappears | ||
| second phase of mitosis, during which the chromosomes line up across the center of the cell | ||
| the third phase of mitosis, during which the chromosome pairs separate and move toward opposite poles | ||
| the final stage of mitosis or meiosis, during which a nuclear membrane forms around each set of new chromosomes | ||
| division of the cytoplasm during cell division | ||
| period of the cell cycle between cell divisions | ||
| a reproductive process that involves only one parent and produces offspring that are identical to the parent | ||
| a form of asexual reproduction in which one cell divides to form 2 idenical cells | ||
| asexual reproduction in which a part of the parent organism pinches off and forms a new organism | ||
| (biology) growth anew of lost tissue or destroyed parts or organs | ||
| (genetics) an organism or cell having only one complete set of chromosomes | ||
| (genetics) an organism or cell having two sets of chromosomes or twice the haploid number | ||
| the mathematical chance that an event will occur | ||
| two parents each form reproductive cells that have one half the number of chromosomes | ||
| the biological process whereby genetic factors are transmitted from one generation to the next | ||
| what an organism looks like as a consequence of its genotype | ||
| genetic makeup of an organism | ||
| trait that will show up in an organism's phenotype if gene is present | ||
| trait that will only appear in the phenotype if organism inherits two of them; covered up by the dominant gene | ||
| a chart that shows all the possible combinations of alleles that can result from a genetic cross | ||
| a comparison of two quantities by division | ||
| a proportion multiplied by 100 | ||
| a mature sexual reproductive cell having a single set of unpaired chromosomes | ||
| female gamete | ||
| male gamete | ||
| process in sexual reproduction in which male and female reproductive cells join to form a new cell | ||
| term used to refer to an organism that has two different alleles for the same trait | ||
| having two identical alleles for a trait | ||
| offspring of crosses between parents with different traits | ||
| an organism that always produces offspring with the same form of a trait as the parent | ||
| the shape of DNA | ||
| threadlike structure within the nucleus containing the genetic information that is passed from one generation of cells to the next | ||
| a process in cell division during which the number of chromosomes decreases to half the original number by two divisions of the nucleus, which results in the production of sex cells |
