Epistasis, Complementation, and Extensions to Mendelian Genetics Flashcards
Study for Genetics Exam 2
1
Q
Variable Penetrance
A
An individual with a particular genotype never develops the phenotype but others do
2
Q
Variable Expressivity
A
The extent in which the phenotype is developed
3
Q
Epistasis
A
When two different genes affect the same phenotype
4
Q
Complementation
A
When two recessive alleles give a dominant phenotype
5
Q
Complementation Groups
A
All members in this group are affected in the same gene
Will all be homozygous recessive unless in a different group
6
Q
A
7
Q
What is the distribution ratio for epistasis?
A
9:7
or 3:1
8
Q
How to tell if a question is asking about complementation?
A
If it is talking about a pathway!
