PPT-1.2 Inheritance of a Single Trait & Response to Selecti

Stevan J Arnold Department of Integrative Biology Oregon State University Thesis Most traits are affected by many genes We can model the inheritance of such traits with a statistical approach . 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. Stevan. J. Arnold.

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). 1/21.

Department of Integrative Biology. Oregon State University. Thesis. The statistical approach that we used for a single trait can be extended to multiple traits.. The key statistical parameter that emerges is the G-matrix.. Human Genetics. . Thomas Hunt Morgan. – (early 1900’s). - Worked with Drosophila (fruit flies).. - Discovered sex chromosomes (X and Y)…Y is shorter than X in length.. - Females = XX Males = XY. 1.
