Homeotic genes contain a homeobox sequence that is highly conserved among very diverse species. The homeobox is the code for that domain of a protein that binds to DNA in a regulatory developmental process. Which of the following would you then expect?

#Unit 11. Evolution and Behavior

That homeotic genes are selectively expressed over developmental time.
That a homeobox containing gene has to be a developmental regulator.
That homeoboxes cannot be expressed in non-homeotic genes.
That all organisms must have homeotic genes.

In goats, a beard is produced by an autosomal allele that is dominant in males and recessive in females. We’ll use the symbol Bb for the beard allele and B for the beardless allele. Another independently assorting autosomal allele that produces a black coat (W) is dominant over the allele for white coat (w). A cross allowed between BBbWw (male) X BBbWw (female). What is proportional of female progeny will beard with black coat?
