| Question | Answer |
|---|---|
| Species | All organisms that can mate with one another and produce viable (fertile) offspring |
| Inherited Trait | traits passed down from parent to offspring; traits you are born with |
| Variation | the difference in a trait Example: trait=number of legs; variation= 2 (humans), 4 (dogs); brown and blue eyes |
| Acquired Trait | traits that can be learned or changed depending on an organism's interaction with its environment |
| Organism | a living thing |
| heredity | the passing down of traits from one generation to another. |
| DNA | a molecule in the nucleus of a cell that carries the instructions of an organism |
| gene | a unit of DNA that is usually located in a chromosome and that controls the development of one or more traits. |
| Chromosomes | strings of DNA inside the nucleus of a cell |
| genetics | the study of how traits are passed down |
| pedigree | a diagram showing the keeps track of family relationships and genetic information |
| gamete | a reproductive cell having a single set of chromosomes (sperm or egg) |
| offsrping | are the young born of living organisms, produced in sexual reproduction of two organisms |
| sperm | Male sex cell |
| egg | Female sex cell |
| cell division | Process by which a cell divides into two new daughter cells |
| nucleus | Control center of the cell |
| mitosis | A process that takes place in the nucleus of a dividing cell, involves four steps: prophase, metaphase, anaphase, and telophase |
| allele | Different forms of a gene eg. (AA, Aa, aa) |
| genes | genes are part of DNA and carry hereditary information passed from parents to children. |
| dominant | dominant version (allele) of a gene shows its specific trait even only if only one parent passed the gene to the child. example brown eyes are dominant over blue eyes B |
| recessive | recessive gene shows its specific trait when both parents pass the gene to the child example bb |
| homozygous | two of the same form of a gene- one from mom and the other from dad example bb, BB |
| heterozygous | two different forms of a gene- one from mom and the other from dad are different example Bb |
| genotype | internal genetic coding passed on from one generation to the next |
| phenotype | outwardly expressed traits or characteristics |
| Survival of the Fittest | Process by which better adapted organisms survive and reproduce.This phrase summarizes natural selection. |
