PPT-Multiple Alleles and Sex-Linked Patterns of Inheritance

Multiple alleles a gene inheritance pattern in which at least three unique alleles are present for one trait the three alleles may interact with each other using any other pattern DominantRecessive Incomplete Dominance Codominance etc. This presentation . builds on session 1 exploring patterns of inheritance. Patterns of inheritance. The objectives of this presentation are to:. Understand how genes are inherited. Understand the differences between the inheritance patterns associated with Autosomal dominant, Autosomal recessive, X-linked recessive and chromosomal abnormalities. be 10/13(midterm-yes . includes all up to now). I have the genetics review up on my page already, it would be wise for you to go ahead and start it. 2. nd. set of journals due 10/7. Incomplete Dominance. What you should know:. The ‘etiquette’ used to represent genetic crosses.. Know what is, and how to represent a monohybrid cross.. Know what is, and how to represent a cross showing sex-linkage.. 14.1 Human Chromosomes. Karyotypes. What is a karyotype?. A karyotype shows the complete diploid set of chromosomes grouped. together in pairs, arranged in order of decreasing size.. Karyotypes. A . What you should know:. The ‘etiquette’ used to represent genetic crosses.. Know what is, and how to represent a monohybrid cross.. Know what is, and how to represent a cross showing sex-linkage.. Chapter 14. In the 1800s the popular inheritance theory was “blending”--offspring were a mixture of their parents. this suggests that organisms will become uniform over time (we know this isn’t true). SBI3U. Mendel Demonstrated. :. Law of Segregation. Law of Independent Assortment. The . alleles. for a gene . segregate independently. . during meiosis. . This applies to alleles located on homologous chromosomes. Mendel discovered the basic principles of heredity by breeding garden peas in carefully planned experiments. Mendel’s Results. Mendel’s 3 Laws. Law of Dominance. Law of Segregation. Law of Independent Assortment.  .
