Web12 apr. 2024 · You can determine if an egg has been fertilized in one of two ways. The first is to crack open a sample egg from your hen and locate the small white spot (4–5 mm) in the yolk; this is called a germinal disc and is the site of cellular division. You only need to do this for one or two eggs to determine if the clutch has been fertilized. WebAt first, cells may be specified, earmarked for a certain fate but able to switch given the right cues. Next, they may become determined, meaning that they are irreversibly committed to a certain fate. Once a cell is determined, even if it’s moved to a new environment, it will differentiate as the cell type to which it's become committed ^5 5.
