Chapter 16 Blog: Simple Patterns of INnheritance

Page history last edited by Garielle Wagnac 13 years ago

On this page you are required to add two items (link to a website, video, animation, student-created slide show, student-created PowerPoint presentation) and one journal article pertaining to a topic in this chapter.  A one-paragraph summary must accompany each item describing the main idea and how it applies to the lecture topic.  Please see the PBWorks help guide for assistance embedding video and other items directly in the page.  I will also produce a how-to video on using tables to wrap text around items and other useful tips.  Please see the syllabus for organization and grading details.


Chapter Summary


  • Mendel created an experiment to observe inheritance with the use of peas. The usage of peas was brilliant because they only exhibit 2 phenotypes for each trait that can be observed. Pea plants can self fertilize so if you wanted to cross over two different plants because you can take a stamen of one plant cross over to a different plant  to have cross fertilization which exactly what Mendel did.
  •  The results of a monohybrid cross is a 3:1 phenotypic ratio which means our of the four possible out comes 3 of the flowers looked the same and one was different form the rest. However, the genotypic ratio is 1:2:1 which means there were 2 flowe rs that contained the same genotype and then 2 others that were totally different from the 3 other flowers. These rations only occur in monohybrid crosses with both gametes from each parent to be heterozygous at the F2 Generation. 
  • The principal of Segregation is that two alleles of a gene separate during gamete production allowing each gamete to contain only one allele.
  • The results of a dihybrid is a phenotypic ratio of 9:3:3:1
  • The  Law of Independent Assortment is where the alleles of different genes assort independently of each other during meiosis.
  • Chromosome Theory of Inheritance
    • explains how the steps of meiosis accounts for the inheritance patterns observed by Mendel. 
    • genes are found on chromosomes contained on DNA 
    • chromosomes are passed from parent to child with the replicated chromosomes from the parent go to the child
    • diploid cell contains homologous pairs of chromosomes, the maternal and paternal sets are homologous 
    • meiosis is the separation of the chromosomes into daughter cells that are haploid due to the homologues chromosomes segregating
    • fertilization is the joining of 2 haploid cell to form a diploid cell

Useful Materials


  • This video is awesome because its like another lecture class but we can use  punnet squares! :P But he seriously does explain things and with the use of the punnet square plus technology he really does make things visual. This is good for visual learners.
  • I could never understand how genetic probability worked but this video goes through part of it and the main site has way other videos to
