Extensions of Mendelian inheritance - Incomplete dominance, overdominance, and codominance
7 important questions on Extensions of Mendelian inheritance - Incomplete dominance, overdominance, and codominance
What is incomplete dominance?
At the molecular level, what is the explanation that flowers can be pink instead of red or white?
At which level is incomplete dominance more likely to be observed-at the molecular/cellular level or at the organism level?
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What is overdominance, or heterozygote advantage?
Why does the heterozygote for sickle cell disease have an advantage?
How can we explain the observation that two protein variants in the Hb^AHb^S heterozygote produce a more favorable phenotype?
- Disease resistance;
- Subunit composition of proteins (homodimer);
- Differences in protein function.
When speaking of blood groups, which allele is an example of a loss-of-function allele?
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
