Chromosomes and Inheritance
| Chapter 3 | Vocab |
|---|---|
| Fertilization | An egg and sperm cell joining to form a new cell in a process. |
| Trait | Specific characteristic that an organism can pass to its offspring through its genes |
| Gene | a sequence of DNA that determines a trait and is passed from parent offspring. |
| Inheritance | The process by which an offspring receives genes from its parents. |
| Allele | A different from of the same gene. |
| Heredity | The trait passing of traits from parent to offspring,it is important to learn about the history behind the science |
| Dominant allele | Is one whose traits always shows up in the organism when the allele is present |
| Recessive allele | Is hidden whenever the dominant allele is present |
| probability | A number that describe how likely it is that an event will occur |
| genotype | An organism;s genetic makeup or combination of alleles |
| phenotype | The organism's physical appearance or visible traits |
| Chromosomes | code of that appears on structures these thread-like structures within a cell's nucleus contain DNA |
| cell cycle | the series of events in which a cell grows,prepares for division,and divides to form daughter cells |
| pedigree | A tool that genetics use to map out the inheritance of traits |
| meiosis | Sex cells(sperm and eggs) are formed through a very specialized process |
| chromatids | Each chromosomes split into two rod-like structures |
| mitosis | cell divide to make 2 genetically identical new cells in a process |
| Asexual reproduction | Genetically identical to the parent |
| Sexual reproduction | two parents combine their genetic |
