Lecture, chapter 3 - Mendelian genetics

Today we covered most of chapter 3 in the textbook, after having our first quiz of the quarter.

We had an overview of how Mendel's experiments lead him to propose his two famous principles:

• Principle of segregation
• Principle of independent assortment

As part of the story of Mendel's progress we talked about the reception his research had when he puylished it (1866), when and why his work was redicovered by other European geneticists at about 1900, and when his results were linked to the recent (at the time) discoveries of mitosis, meiosis, and chromosomes.
We covered monohybid and dihybrid crosses, concepts of dominance and recesiveness, and phenotypic proportions resulting from each one of these.
We also started covering complex phenotypes and the phenomena that explains their patterns under the light of Mendelian inheritance.

For Monday: Read chapter 4 in the textbook...!
