Answer:
Approximately how many separate Hox genes are in our human genome is (b) 13.
Step-by-step explanation:
There are approximately 13 separate Hox genes in our human genome. Hox genes are a family of genes that play a crucial role in the development and patterning of the body during embryonic development. They are responsible for the formation of body structures along the anterior-posterior axis.
These 13 Hox genes are organized into four clusters on different chromosomes. Each cluster contains genes that are expressed in specific regions of the developing embryo, contributing to the proper formation of body segments and structures. The expression and regulation of Hox genes are highly conserved across various species and are fundamental to the intricate process of embryonic development.
Option b is correct.
