Hox Genes and Body-Plan Specification
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Hox genes are a conserved gene family, expressed in chromosomal order, that specify which structures form at each anterior-posterior position, using the transcription-factor regulation Bio 1329 introduces.
Show
A mutated Hox gene in fruit flies can cause legs to grow where antennae normally form.
Watch for
Hox genes specify which structure forms at a position — they do not build that structure's cells themselves.
