Definition
A structure within the cell that bears the genetic material as a threadlike linear strand of DNA bonded to various proteins in the nucleus of eukaryotic cells, or as a circular strand of DNA in the cytoplasm of prokaryotes and in the mitochondrion and chloroplast of certain eukaryotes. |

Term
|
Definition
| One member of a pair (or any of the series) of genes occupying a specific spot on a chromosome that controls the same trait. |

| The location of a gene (or of a significant sequence) on a chromosome, as in genetic locus. |

Term
|
Definition
| A Mendelian law which holds that one from the pair of alleles coding for a particular trait would be expressed whereas the other is unexpressed. The allele expressed for a particular trait is regarded as the dominant whereas the other is considered recessive. |

Term
|
Definition
| Gregor Mendel's law stating that paired alleles separate during gamete formation. Each gamete contains only one copy of every paired unit factors. |
|
|
Term
| Law of Independent Assortment |
|
Definition
Mendelian law stating that for every pair of unit factors, each of them would assort independently into the newly formed gametes. |
