Question

You discover a new phylum of animal and call it the Lagramphia, After doing some research you find that on one of its chromosomes it has six Homeobox (Hox) genes in the following orientation: You then find that there are six distinct expression regions (labeled A through F below) for these genes that correspond with the different body regions of the organism. Match the Hox genes with their expression region in the diagram of Lagramphia above You find a seventh Hox gene that is located between Hox6 and the end of the chromosome. Predict where this gene would be expressed in Lagramphia.

Explanation / Answer

hox 1 gene will control the expression region A

hox 2 will control the expression region B

hox 3 will conttrol the expression region C

hox 4 will control the expression region D and so on...

hox 7 will control the expression region below expression region G , that is it will control the development of tail.

genes arranged in linear order will , affect the develpoment linearly
