Question

In some eggs, future organs can be demarcated even before cleavage begins. This type of development is called as

• A. Mosaic development
• B. Regulatory development
• C. Gynogenesis
• D. None of the above

Answer 1

The correct option is A Mosaic development

Mosaic development is when destruction of one cell of a two cell embryo results in the development of only one half of embryo.

Regulatory development is when each cell removed from an early embryo forms a complete organism.

Gynogenesis is development in which the embryo contains only maternal chromosomes due to activation of an egg by a sperm that degenerates without fusing with the egg nucleus.
Thus, the correct answer is option A.
