I'm not sure how basic and far back the squash threads go. Crossing squash is pretty easy. If you are particiular you tape a female flower of the mother squash before it opens (inflated ovary on a short stalk. After it would have opened. Then you rip an anther off the father squash (no inlation, longer stalk, contains anthers full of pollen when ripe). You open your female flower dab that anther on the stigma and tape that flower back closed again. If you aren't particular just grow both varieties together save your seed and they'll cross on their own eventually.
