Developmental Mechanisms Problem Set

Problem 7: Role of homeotic genes in development

Homeotic genes:

A. Determine the direction of developmental fates of groups of cells in a segment of the embryo.

B. Include a DNA sequence called the homeobox that is similar in all homeotic genes.

C. Are altered in homeotic mutations such as Antennapedia, causing abnormal development of the head.

D. Are similar between mice and flies for both structure and order on the chromosome.

E. All are true.
All of the above are true statements about homeotic genes.
