In a developing embryo, tissues such as muscle and nerve are produced by A - Scottish Highers Human Biology - Question 1 - 2016

In a developing embryo, the formation of tissues such as muscle and nerve primarily occurs through mitosis in somatic cells. Mitosis is the process by which somatic (or body) cells divide to produce two identical daughter cells, allowing for growth and development of tissues. In contrast, meiosis is involved in producing germ cells for reproduction, not in the development of somatic tissues.
