In a developing Drosophila melanogaster embryo, a hierarchy of gene regulatory interactions subdivides the embryo to regulate progressively finer details of patterning. For each of the following proteins, indicate which expression pattern (1 to 4) in the schematic drawing below is more appropriate. Your answer would be a four-digit number composed of digits 1 to 4 only, with each digit used once, e.g. 3412.
( ) Hunchback (product of a gap gene)
( ) Engrailed (product of a segment-polarity gene)
( ) Bicoid (product of an egg-polarity gene)
( ) Even-skipped (product of a pair-rule gene)
Definitions:
Predicted Value
The estimated value based on a regression or other predictive model.
Response Surface
A graphical representation used in statistical analysis to visualize the relationship between multiple independent variables and one or more dependent variables.
Polynomial Model
A regression model where the relationship between the independent variable and the dependent variable is expressed as an nth degree polynomial.
Independent Variable
The variable in an experiment that is manipulated or changed by the researcher to observe its effect on the dependent variable.
