It's called the germinal disc or blastodisc - a small, circular, white spot (2-3 mm across) on the surface of the yolk; it is where the sperm enters the egg. The nucleus of the egg is in the blastodisc.
There is a easy way of figuring out. Look below Earth is a tiny dot compared to the solar system. The solar system is a tiny dot in the milky way. The milky way is a tiny dot to the galactic clusters. The galactic cluster is a tiny dot to a super cluster. The super cluster is a tiny dot to the Void. The void is a tiny dot to the universe.
Depends on the eggs. Chicken eggs are visible (of course) A Human egg cell is barely visible as a tiny dot. Eggs of some other animals may be too small to see without magnification.
The tiny dot bugs spotted in the garden recently are likely aphids.

We currently have a turkey laying eggs. She is a bronze turkey, not white. Her eggs are a very light brownish cream color. They have hundreds of irregular reddish speckles, some the size of a pen dot, all the way up to about 2mm.
Japan's flag is white with a red dot in the center.
