Gene Dosage | Gene Dosage Analysis | Gene Dosage Effects |

The video discusses the concept of gene dosage, which refers to the number of copies of a specific gene present in an organism's genome. The video explains that changes in gene dosage can have significant phenotypic consequences and that the appropriate dose of gene expression is necessary for cellular function and health. Additionally, the video notes that most genes found in a cell are expressed as autosomal genes and are present in two copies, with alterations to this dosage associated with many genetic health problems. Furthermore, the video explains that genes closer to the origin site of replication are replicated first and are present in two copies for a longer time than genes farther away from the origin site, leading to differences in gene expression depending on the position on the chromosome.
