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 |

Need Notes?
While we strive to provide the most comprehensive notes for as many high school textbooks as possible, there are certainly going to be some that we miss. Drop us a note and let us know which textbooks you need. Be sure to include which edition of the textbook you are using! If we see enough demand, we'll do whatever we can to get those notes up on the site for you!
