Sundberg interpreted many aspects of trilobite evolution in terms of homeotic change. |
If the candidate mutation is involved in homeotic gene silencing, an increase in the numbers of sex comb teeth on the adult second and third legs is expected. |
The evolution of homeotic mutants, according to Simpson, still depended on selection acting on populations of individuals. |
These genes encode proteins that are involved in regulating the expression of homeotic genes by changing chromatin structure. |
Mutation and overexpression of labial result in altered homeotic gene expression in the tritocerebrum. |
In these plants, some sepals showed homeotic transformations to carpels, becoming fused and presenting ovules and stigmatic papillae. |
