Which statement is true of hox genes?
Group of answer choices
A. they regulate development of body regions and are found in all animals
B. they control the functioning of cells and are found in all life
C. they control growth and development in plants
D. they are only found in insects and control segmentation
DNA sequences called homeoboxes help homeotic genes in animals direct development. Given that they are common to flies and mice, explain why these animals are so different.
An adult human has a flat face with a small jaw and large cranium. An adult chimpanzee has a large jaw and small cranium. Both juvenile chimps and humans have heads similar to adult humans. Which of the following is a reasonable explanation for this pattern?
Group of answer choices
A) genes that modify skull shape are not expressed in chimps during development
B) head shape is controlled by cytoplasmic determinants
C)genes that modify skull shape are not expressed in humans during development
D) chimps and humans have completely different genes controlling the formation of the head
