During apomixis does the normal fertilization (egg cell + male nucleus 1) take place or just the fusion of two synergid nuclei?

Apomixis is a modified form of asexual reproduction in which seeds are formed without fusion of gametes.
It includes the process whereby a diploid cell of the nucellus develops into an embryo, giving a diploid seed with genetic constitution identical to the parent.

Apomixis is usually associated with polyploidy. The organism that can reproduce by apomixis is called an apomiet. Examples- Dandelions, citrus and certain grasses.
