Why are sperm cells different if they are all cells from the same parent?
In: Biology
You have two copies of each autosomal chromosome. One from your father and one from your mother.
When a person produces sperm (or mature eggs) there’s a process called meiosis which separates one copy of each. It might be from your father, your mother, or they might mix and match in a process called recombination. This is different for each chromosome…
As you can imagine, this leads to tons of possible combinations of genetic material.
