How do Pedigree charts work?

Question

Can someone please explain pedigree charts to me? All I know is that squares represent males and circles represent females. I also know that when one of the shapes is colored, it means that that person is affected by something. So, what does it mean when the shape is colored half-way? I also heard that it is organized by age as well.. from youngest to oldest (left to right)/. So can you please answer these questions for me and aslo add some more information that would be helpful.

Thank you.

The squares and circles that you mention are NOT STANDARD genealogy symbols.  The core purpose of a pedigree chart is to show direct ancestry only, in a "tree" format.

So.. you are the root person to the far left... it branches into father and mother, going to the right.  Each of those will again branch to show the father/ mother of those.  Normally, the dates of birth/ death will be included just under the names.

The lines leading to father and mother are self explanatory.. no reason for any squares. Father is a male, mom is female.

The pedigree chart and family group sheet are the two STANDARD forms used. A family group is text based, dad/ mom at the top, with their details, including names (only) of the respective parents for each.  Below, you list the children of that relationship only, in order of birth, with their facts.

I am guessing that what you have has been given to you, and is someone's own creation.  The whole reason to use standards, is that they remain understandable by anyone, without the need for any explanation.
