The back of a mouse would correspond to its ________________ axis.
During development, certain cells will sometimes release signaling molecules that bind to receptors on other neighboring cells, which then causes those neighbors to assume a certain sort of developmental fate. This process is referred to as induction.
True or False
Even-skipped is an example of this category of Drosophila developmental genes.
A mutation in the Drosophila bicoid gene leads to _____________________________.
Loss of head structures in the larvae
A morphogen influences the fate of a cell in a concentration dependent manner.
True or False
A cell sends a diffusible signaling molecule to a neighboring cell. This signaling molecule binds a receptor on the cell surface on that neighbor cell triggering a series of events that cause that cell to develop as a neuron. This process is best described as ______________________.
The primary model organism that is used to study plant development is ____________.
What is the function of the homeodomain?
A cell that can produce all of the cell types in an adult organism is said to be __________.
In what model organism is the lineage of every cell known?
Which of the following development stages of Drosophila occurs before the other three?
A. cellular blastoderm
D. syncytial blastoderm
In Drosophila, a mutation in one of the __________ genes is likely to lead to a transformation of one body part into a different body part (e.g. antennae that are transformed into legs).
In what ways do cells respond to positional information during animal development?
Depending on the signals received they could respond through cell death via apoptosis, cell division, or cell migration
