So back to the basics...I get way to many questions about breeding. O.K Ready using the Smith's again you know that family down the street. For the most part genes are inherited from our parents. But certain genetics in individuals are mutant or defective traits that develop on their own. ie: Albinism the absent of pigment in the skin.Unable to produce melanin to change color of skin eyes and hair. Or in the plant world no fruit, leaf structure or absence of color or change in normal color. So back to the Smith's both parents carries the gene for albinism (faulty gene) and one normal gene. Both parents can produce melanin and look normal.
They have four kids..two will be carriers like their parents. one good gene one bad. because each child inherits one gene from Mom one from Dad. Kid one both healthy genes. Kid Two and Three each receive one of each one good one bad still can produce melanin. Kid Four both faulty genes....Say hello to Albino Boy. IN PLANTS THE SAME GENETICS APPLY. But in a bigger scheme that's why a bag of seeds can say Blue Dream but it can look like any combination of the parents and each trait varies because they all following the same rule sets of four x each trait. That's why if you get a plant that looks and smells like Santa Cruz Haze more than Blue Dream it's Strain Genetics. Only true copy is a clone.
