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. |
