| Term | Definition |
|---|---|
| Genetics | The science of how traits are inherited through alleles passed from one generation to another. |
| Inheritance | Inheritance is the practice of passing on property, titles, debts, rights, and obligations upon the death of an individual. |
| Gregor Mendel | Did the first recorded scientific study on how traits are passed from one generation to the next. |
| Nucleus | The structures inside a cell that directs the cells activities |
| Chromosomes | Thread like strands of DNA and protein in a cell nucleus that carry the code for the cell characteristics of an organism. |
| Gene | The segment of DNA on a chromosome that directs the making of a specific protein, thus controlling traits that are passed to offspring. |
| Allele | a different form a gene may have for a trait. |
| Dominant allele | dominance in genetics is a relationship between alleles of one gene, in which the effect on phenotype of one allele masks the contribution of a second allele at the same locus. |
| Recessive allele | A recessive allele is a variety of genetic code that does not create a phenotype if a dominant allele is present. |
| Phenotype | the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment. |
| Genotype | The genetic makeup of an organism for a trait. |
| Homozygous alleles | Homozygous is a word that refers to a particular gene that has identical alleles on both homologous chromosomes. |
| Heterozygous alleles | In diploid organisms, heterozygous refers to an individual having two different alleles for a specific trait. |
| Mitosis | a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth. |
| Meiosis | To put that another way, meiosis in humans is a division process that takes us from a diploid cell one with two sets of chromosomes to haploid cells |
| Punnett square | The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. |
| Feature | a distinctive attribute or aspect of something. |
| Trait | a genetically determined characteristic. |
| Adaptation | Any characteristic of an organism that makes it better able to survive in its environment. |
| natural selection | the process whereby organisms better adapted to their environment tend to survive and produce more offspring |
| sexual reproduction | the production of new living organisms by combining genetic information from two individuals of different types of sexes. |
| asexual reproduction | Asexual reproduction is a type of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only; it does not involve the fusion of gametes, and almost never changes the number of chromosomes |
| codominance | Codominance is a form of dominance wherein the alleles of a gene pair in a heterozygote are fully expressed |
| mutation | A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. |
| Charles Darwin | Person who developed the theory of evolution. |
| Incomplete dominance | the production of phenotype that is intermediate to those of the two homozygous parents. |
