Pie

Answer:

Following Statements are true.

1. Cells receive molecular signals that communicate their position in relation to other cells.

3. Differential gene expression affects the developmental process in animals.

4. Positional information controls pattern formation.

6. Homeotic genes code for transcription factors that control the development of segment-specific body parts.

Explanation:

The formation of an eukaryotic organisms's spatial organization which includes organ formation and tissue arrangement is called as Pattern formation.

Molecular signals are received by cell. This phenomenon collectively refereed as positional information. Through this phenomenon cells are informed about their locomotion with respect to body axes and other cells. Regulation of pattern formation is controlled by Positional information.

When body axes is established a gene called homeotic gene start working as regulatory genes. This gene identify specific body segment in an organism which results in the formation of segment-specific body structures in the correct locations on the body.
