Read Section 6.3:
Genetics After Mendel pages 168-178
In notebooks, define and answer:
Incomplete Dominance
Know how this differs from straight Mendelian genetics seen in
section 6.2.
Give an example of this type of inheritance.
Co-dominace
Understand how to represent the two alleles in the genotype.
Give an example of this type of inheritance.
Multiple Allelism
Give an example of this type of inheritance.
Understand how to write the three different alleles for ABO Blood
Group System in humans (Using capital I, lower case I, and A, B, AB
superscripts)
Multifactorial Traits
Continuous vs Discontinuous Distributions.
Give examples of these two types of phenotypes.
Gene Interactions and the Environment
Describe areas where NATURE vs NURTURE has an effect of an individuals characteristics.
Gene Linkage
“Linkage Groups”
Copy Punnett Square – Figure 6.18
Copy Possible Gametes during Meiosis – Figures 6.19 and 6.20
Understand how the predicted Mendelian outcomes and the Observed outcomes came about by the
genes being linked (on the same chromosome) versus being independent (on different
chromosomes (as observed by Mendel in the Pea Plants)).
Crossing Over
Recombinants
Gene Maps
What did Sturtevant reason about Gene Maps?
What do gene maps tell us?
Go over example problem, page 177-178 on mapping.
