The products of Hox genes __________.
A
may cause polyploidy in some plants
B
control the rate of timing and developmental events
C
can cause paedomorphosis
D
result in heterochrony
E
provide positional information in animal embryos
Verified step by step guidance1
Understand that Hox genes are a group of related genes that control the body plan of an embryo along the head-tail axis.
Recognize that the primary role of Hox genes is to provide positional information to cells, which helps in determining the identity and arrangement of body parts.
Note that while Hox genes are crucial for developmental processes, they do not directly cause polyploidy, paedomorphosis, or heterochrony.
Acknowledge that Hox genes influence the expression of other genes that control the rate, timing, and spatial organization of developmental events.
Conclude that the products of Hox genes provide positional information in animal embryos, guiding the formation of structures in the correct locations.
