Please tell me what the right answers are and why?

macmillan learning Certain genes are expressed in multiple regions of a developing embryo and affect the development of different tissues. By which mechanisms can a single gene produce different outcomes in multiple tissues? Signaling proteins can exist in gradients whose concentration affects signal transduction. Tissue-specific differences in silencing can affect transcription of the gene A duplicated gene can evolve independent functions from the original gene Alternative splicing results in different isoforms that can have tissue-specific effects.

Explanation / Answer

Certain genes are expressed in multiple regions of a developing embryo and affect the development of different tissues. The mechanisms by which the single gene can produce different outcomes in multiple tissues are as follows,
