What is the correct order of expression of the genes listed below in the determination of segmentation in Drosophila(1) Segment polarity genes(2)Hox genes(3)Gap genes(4)Pair rule genes

The correct order of expression of the genes listed below in the determination of segmentation in Drosophila is "Hox genes > Gap genes > Pair rule genes > Segment polarity genes"

Order: 2 > 3 > 4 > 1

Explanation:

The master regulator genes are that guide the creation of specific body segments or structures known as "Homeotic genes". Since these genes are active in segment patterning, the gap genes, pair-rule genes and segment polarity genes are designated as segmentation genes.

the answer is c) an oak tree

many phylogenetic trees have a single lineage at the base representing a common ancestor. a lineage that evolved early from the root and remains unbranched is called basal taxon. when two lineages stem from the same branch point, they are called sister taxa.
