Causes of ALS. ALS is a somewhat diverse and decidedly mystifying disease. In more than nine out of every 10 cases diagnosed, no clear identifying cause of the disease is apparent, that is, patients lack an obvious genetic history, complete with affected family members.
Here is a list of some of the more common varieties, along with fruit and plant descriptions. 1  Aristocrat - this variety features a waxy skin and is medium green in color.  Black Zucchini - very dark green skin and almost white flesh, very common variety of zucchini.
What they all have in common are a soft, thin, edible skin with soft seeds inside (which actually make them a fruit by the way) and the fact that they can be eaten raw, unlike their cousins (winter squash). Zucchini is the most well known in the summer squash category. Summer squash includes zuccini (black, green or yellow), crooked neck, straight neck, scallop, butter blossom, gourmet globe and sun drops.
