| Term | Definition |
|---|---|
| Allele | one of two or more forms of a gene that are made by mutation and are found at the same place on a chromosome. |
| autosome | any chromosome that is not a sex chromosome. |
| Codominance | Relationship between two versions of a cell |
| dihybrid | a hybrid that is heterozygous for alleles of two different genes. |
| dominate alele | an allele that produces the same phenotype whether its paired allele is identical or different |
| genotype | the genetic makeup of an individual organism. |
| hetrozygous | a pair of genes where one is dominant and one is recessive |
| homozygous | a pair of matching alleles, which are the two genes that control a particular trait |
| monohybrid | a hybrid that is heterozygous with respect to a specified gene. |
| multiple allele | an allele of a genetic locus having more than two allelic forms within a population. |
| phenotype | the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment. |
| punnet square | The Punnett square is a diagram that is used to predict an outcome of a particular cross or breeding experiment |
| recessive allele | n an allele that produces its characteristic phenotype only when its paired allele is identical |
| sex chromozone | A type of chromosome in the genome that is involved in the determination of the sex as well as the development of sexual characteristics in an organism. |
| sex-linked trait | A trait associated with a gene that is carried only by the male or female parent. |
| test cross | It is a mating in which an individual showing a dominant phenotype is crossed with an individual showing its recessive phenotype. |
| apoptosis | a genetically regulated process leading to the death of cells and triggered by the presence or absence of certain stimuli, |
| cell cycle | The cell cycle or cell-division cycle is the series of events that take place in a cell leading to its division and duplication that makes two daughter cells |
| centreole | divides in perpendicular fashion during mitosis |
| chromere | One of the serially aligned beadlike granules of concentrated chromatin that constitutes a chromosome during the early phases of cell division. |
| chromatin | the readily stainable substance of a cell nucleus, consisting of DNA, RNA, and various proteins, that forms chromosomes during cell division. |
| chromosone | Chromosomes are the things that make organisms what they are |
| crossing-over | A process occurring during meiosis wherein two chromosomes pair up and exchange segments of their genetic material. |
| cytokinesis | the physical process of cell division |
| diploid 2n chromosome number | Having two sets of chromosomes or double the haploid number of chromosomes |
| gamete | Gametes are the cells used during sexual reproduction to produce a new individual organism or zygote |
| haploid n chromosome number | Biology. pertaining to a single set of chromosomes. |
| homologous chromosone | a chromosome with the same gene sequence as another |
| meiosis | Meiosis is the process by which the nucleus divides in all sexually reproducing organisms during the production of spores or gametes. |
| mitosis | The process where a single cell divides resulting in generally two identical cells, each containing the same number of chromosomes and genetic content as that of the original cell. |
| somatic cell | one of the cells that take part in the formation of the body |
| synapsis | the pairing of two homologous chromosomes that occurs during meiosis. |
