Lecture 14 Flashcards
1
Q
Spatial Colinearity
A
perfect correlation between the order of genes and the anterior to posterior location of the gene expression in the embryo
2
Q
Temporal Colinearity
A
genes at the 3’ end tend to be expressed earlier in development than genes at the 5’ end
3
Q
Quantitative Colinearity
A
multiple hox genes are expressed in the same place gradients of expression also correspond with chromosomal location
4
Q
Gene Expression
A
genes operate as switches, on off, or like a gradient
5
Q
Nonfunctionlization
A
genes duplicate, mutations attack the duplicate leading it to not be functional
6
Q
Redundancy
A
second is redundant, natural selection chooses both genes
7
Q
Neofunctionalization
A
the duplicate could get new functions
8
Q
Subfunctionalization
A
sub functions of those genes
