Reproduction Unit
Stack for the Reproduction Unit Study Guide
| Question | Answer |
|---|---|
| Define reproductive success | how many successful offspring an individual organism produces |
| Give an example of a behavior that increases reproductive success | Birds knowing when an egg is not their own increases their own reproductive success |
| Give an example of a physical trait that increases reproductive success | the longer the tail of a male Long-tailed Widowbird, the more females is has eggs with |
| Are animal mating behaviors affected by only genetics, only environment or a combination of the two? | Both |
| What is the purpose of animal mating behavior? | to increase the chances of reproductive sucess |
| List three examples of plant adaptations (physical features) that attract pollinators | Smell Color Height |
| Are plant traits affected by genetics, environment, or both? | Both |
| Define trait | a specific characteristic that varies from one individual to another |
| What causes inherited diseases? | Genes! |
| True or False: Sexual reproduction results in offspring that are genetically that are genetically identical to the parents | FALSE |
| Define fertilization | a male sperm and female egg merge to form a fertilized egg |
| What type of reproduction requires fertilization? | Sexual` |
| Define sexual reproduction | the process in which a sperm and egg merge to create offspring that inherits traits from both |
| What types of organisms reproduce sexually? | Multicellular organism |
| How much genetic information does the offspring inherit from each parent in sexual reproduction? | 50% from each |
| Define asexual reproduction | the process in which an organism creates an identical copy w/out sex cells |
| What type of organisms reproduce asexually? | Unicellular and some multicellular |
| How much genetic information is inherited by the parent in asexual reproduction? | 100% |
| Where is the genetic information contained in the Cell? | Nucleus |
| Organize the following from largest to smallest CHROMOSOMES CELLS GENES | Cells > Chromosomes > Genes |
| Define mutation | a change in DNA that could lead to a different trait |
| Write "3 out of 4" (75%) as a ratio | 3:1 |
| Define dominant | one copy of an allele or gene rises to become an observable trait (always expressed) |
| What type of letter represents the dominant allele? Give an example | Upper case (I) |
| Write both versions of a dominant genotype | II or Ii |
| What type of letter represent the recessive allele? Give an example | Lowercase (i) |
| Write a recessive genotype | ii |
| What is a Punnett Square? | a diagram that shows the possibilities of traits for an offspring |
| What type of reproduction is modeled using Punnett Squares? Explain | Sexual Reproduction is modeled using Punnett Squares because asexual reproduction creates an organism identical to the parent no matter what, there are no possibilities |
| How many copies of each chromosome does a person have? | 2 |
| How many copies of a gene does a person have? | 2 |
| What did Gregor Mendel discover? | The patterns of traits found during sexual reproduction |
| What organism did Mendel study? | Pea Plants |
