Which of the following statements about pattern formation are true? . view available hint(s) select the four statements that are true. a. the process of pattern formation involves segmentation of the body but does not involve the development of segment-specific body parts. b. homeotic genes code for transcription factors that control the development of segment-specific body parts. c. differential gene expression affects the developmental process in animals. d. positional information controls pattern formation. e. homeotic genes establish major body axes. f. cells receive molecular signals that communicate their position in relation to other cells. g. pattern formation begins in adult animals.

The correct answer is b), c),  d), and f)

Pattern formation is the development of a multi-cellular organism's spatial organization, which includes tissues and organs arrangement.

Cells receive molecular signals, which are together known as positional information as it provides information to cells about their location with respect to other cells and to the axes of body. This indicates that pattern formation is regulated positional information. Homeotic genes are regulatory genes that work after the formation of body axes ( such as dorso- ventral and anterior- posterior axis) in the organism. These genes identify particular segments in body of an individual, which ultimately leads to the formation of segment-specific body structures ( such as head thorax and abdomen in drosophila) in the correct location and order.Differential gene expression affects the developmental process in animals.

Thus, option b), c), d), and f) are true statements regarding  pattern formation.
