This is additive color. Red, green and blue are the primary colors of white light. All three colors will result in white, the absence of all three will produce black. When two primary colors of light are added together, you get a color that is brighter than either of its components.
The most obvious way is to put it in an incubator. and see if there is any growth. However, this is not the. most practical way when you are selling eggs for human. consumption. In that case, the best way to tell a fertile. egg is to examine the germ on the egg's yolk to see if. it has divided. The germ is also called the Blastoderm and is. where the baby chick begins to grow. The germ is. located on the surface of the yolk and appears as a light. spot.
Ovulation lasts for 12 to 48 hours, but you are potentially fertile for up to seven days. (And maybe up to 10 days, according to the most optimistic studies.) This is because sperm can survive up to 5 days in the female reproductive tract. Ovulation is when an egg is released from an ovary. That egg survives for up to 48 hours before it can no longer be fertilized by sperm. This short time may be considered the ovulation period. However, your total fertile period is how long the egg is fertile and how long sperm can wait for the egg combined. This is known as your fertile window. While you are possibly fertile for seven days out of your cycle, the odds of conceiving at the far ends of that time period are small.
