Variable phenotype Flashcards
1
Q
How can we get variability in the phenotype of a trait even if it is controlled by the same gene?
A
Complex gene interactions and environmental factors
2
Q
Is it possible to have a carrier of a dominant allele that isn’t WT that is showing the WT phenotype?
A
Yes, due to variable penetrance and expressivity
3
Q
What is variable penetrance?
A
Whether the phenotype of the same alleles shows or not. Is yes or no
4
Q
What is variable expressivity?
A
How much that phenotype of two of the same alleles is expressed. Is a lot or a little
