Shown Below Is a List of Gene Classes That Play $\quad$

Shown below is a list of gene classes that play a role in Drosophila development.
$\quad$$\quad$$\quad$$\quad$$\quad$ homeotic genes
$\quad$$\quad$$\quad$$\quad$$\quad$ gap genes
$\quad$$\quad$$\quad$$\quad$$\quad$ segment-polarity genes
$\quad$$\quad$$\quad$$\quad$$\quad$ maternal-effect genes
$\quad$$\quad$$\quad$$\quad$$\quad$ pair-rule genes

(i)Describe the role of each class of genes and the impact that a mutation in the class has on Drosophila development.
(ii)The different classes of genes function at different times during Drosophila development.Put the gene classes in order,from earliest to latest.
