Reproduction and Development
| Question | Answer |
|---|---|
| What are the 2 types of reproduction? | Asexual and sexual reproduction |
| What is asexual reproduction? | involves one parent and results in one or more offspring that is genetically IDENTICAL to the parent. |
| What is sexual reproduction? | involves 2 parents. Offspring has some genetic material from both parents. |
| What is a gamete? | A sex cell such as an egg or sperm. |
| How are genes carried? | The genes are carried on chromosomes in the sex cell. |
| What is the male sex cell called? | Sperm |
| What is the female sex cell called? | Egg |
| What is cloning? | It is a way of making identical genetic copies of the original cell. |
| What is cellular division? | The orderly separation of one cell into 2. The genetic information is duplicated exactly. |
| What is mitosis? | The process when the cells genetic material divides creating 2 complete sets of the cell. A copy of the genetic material is distributed to each cell. |
| What is meiosis? | The process when the cells genetic material divides with half of the genetic material. |
| What is fertilization? | When the sperm and the egg unite |
| What form of cellular division produces the sex cells? Mitosis or meiosis | Meiosis |
| During mitotic division, what is the total number of cell divisions? | 1 |
| During meiotic division, what is the total number of cell divisions? | 2 |
| Is there an exchange of genetic material between chromosomes during mitotic division? | No a complete copy |
| Is there an exchange of genetic material between chromosomes during meiotic division? | yes |
| What is the number of functioning cells produced from the original cell during mitotic division? | 2 |
| What is the number of functioning cells produced from the original cell during meiotic division? | 4 sperm or 1 egg |
| What is the genetic makeup of the final cell production during mitotic division? | Same as the original. |
| What is the genetic makeup of the final cell production during meiotic division? | Each containing half of the genetic information of the original |
| What is the function of cells produced in multicellular organisms during mitotic division? | Growth or replacement of body cells |
| What is the function of cells produced in multicellular organisms during meiotic division? | Combine to form the zygote for reproduction. |
| What is a zygote? | gametes that are united and form a cell that contains all of the genetic information needed by the offspring. |
| What is recombination? | Genes from the parent cells combine when fertilization occurs |
