| Questions | Answers |
|---|---|
| What is Genetic Drift? | Random changes in the frequency of genetic traits from one generation to another |
| What is Gene Flow? | Admixture through migration and interbreeding |
| What is Mitosis? | The duplication of non-sex cells |
| What is Miosis? | The duplication of sex cells |
| What is a Somatic cell? | A body cell, not a sex cell |
| Where is DNA stored in the cell? | In the nucleus |
| What are DNA's three functions? | Replication of all cells, not just sex cells. Translation. And to transfer info to offspring (meiosis) |
| Adaptations are both cultural and biological. The interaction of these adaptations is | Biological Anthropology |
| Darwin's important ideas were | Natural Selection; Survival of the fittest |
| The branching pattern in evolution can also be called | Cladogenesis |
| Genes are located on the | Chromosomes |
| What is a chromosome? | A string of genes contained in the cell nucleus |
| All cells have the same # of chromosomes except | Sex cells |
| How many pairs of chromosomes do human sex cells have? | 23 |
| How many pairs of chromosomes do regular human cells have? | 46 |
| Who determines the sex of the child? | The Male because he carries XY whereas the female carries XX |
| What is the Founder Effect? (A.K.A. Sewall Wright Effect) | The reduced genetic diversity that results when a population is descended from a small number of colonizing ancestors. |
| How did Linnaeus structure taxonomy? | He gave each plant and animal a higher-level genus name and a lower-level species name. |
| What is Mitochondrial DNA? | A kind of miniature chromosome containing 37 genes that is inherited just from the mother. |
| What is RNA? | A nucleic acid present in all living cells. Its principle role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins. |
| What is DNA? | A self-replicating material present in nearly all-living organisms as the main constituent of chromosomes. It is the carrier of genetic information. |
| What are the relationships of DNA bases? | A with T and C with G |
| A non-disjunction is when | Chromosome pairs fail to separate during meiosis or mitosis and result in an incorrect number of chromosomes in the person's genome. |
| Darwin used Malthus's five observations, which were | That most pairs of parents produce multiple offspring, an organisms population size typically remains the same, population is limited by food supply, members compete for food access, and no two members alike (variation exists). |
