  1. Genetics Review12/11/12

  2. Of the following genotypes, which gene pair(s) would express a dominant phenotype? • DD • Dd • dd • Tt • tt

  3. Compare and contrast sexual and asexual reproduction in terms of • Parents • Number of offspring • Adaptations • Genetic similarness of offspring compared to parent

  4. What are the 4 types of Asexual reproduction? Which one is common amongst single-celled organisms? Which one is common amongst plants? Which one is where a “mini me” shoots out of the original organism? Which one regrows parts?

  5. Does pollination of a flower cause new flowers to be the same genetically or different? So is this Asexual reproduction or Sexual?

  6. During Binary Fission, before the cell splits … explain the genetic material (DNA) of the new cells in comparison to the original cell (parent).

  7. Julie’s cat had babies. 6 of the 8 kittens were short-haired and the other 2 kitten were long-haired. What should you conclude about this?

  8. What does Nn mean to you? What about AA? Or jj?

  9. In OompahLoompas, green hair is dominant to brown hair. If a baby Oompah inherits a green hair allele from the mom and brown hair allele from the dad, what color hair will baby OompahLoompa have and why?

  10. The genes that code for an organisms traits are located in? ____________ which is part of ______________ Which are found in the ____________ of a cell.

  11. In dogs, pointed ears are dominant to the recessive floppy ears. If we cross a floppy-eared dog with a purebred dog that has pointed ears, which of the following will be the resulting genotype? • Floppy ears • Pointed ears • Ff • FF • ff

  12. A trait that always shows when present is ______ • Recessive • Dominant • Homozygous • Heterozygous

  13. Which of the following would produce an offspring with the greatest amount of variation? • Bacteria splitting into 2 • Starfish regrowing a couple of broken arms • A puppy being born • A Potato plant that is cut and the runner is repotted to grow more potato plants

  14. Explain what a gene is? What do they control? How do we get them?

  15. When we talk about heredity, we are talking about inheriting traits from other generations. So what exactly is heredity?

  16. In OompahLoompas, gray faces were dominant to orange faces. So if we breeded an orange faced Oompah with a gray faced Oompah and all of our offspring were gray faced, then what do we specifically know about the gray faced Oompah?
