1. a DNA sequence found in genes that control the development of body parts in animals and plants
Usage: biology; genetics

Examples

• The homeobox genes play a crucial role in determining where limbs develop on an embryo.
• Scientists discovered that mutations in homeobox sequences can cause developmental abnormalities.
• The homeobox is highly conserved across different species, from flies to humans.
• Researchers study homeobox genes to understand how body plans are established during development.
• The fruit fly's homeobox genes helped scientists identify similar sequences in mammals.
• Homeobox proteins act as transcription factors that regulate other genes during embryonic development.
