Wikipedia
单性生殖又称为孤雌生殖,是动物或植物的卵子,不经过受精过程,而单独发育成后代的生殖方式,区别于无性生殖。
单性生殖一般发生在多种植物和无脊椎动物中,但也有一些脊椎动物如某些爬行动物[1](如钩盲蛇、红尾蚺、科摩多巨蜥、哀鳞趾虎、新墨西哥鞭尾蜥),在一些特殊的鸟类[2]和鲨鱼品种(如窄头双髻鲨、条纹斑竹鲨、黑边鳍真鲨)中也会出现[3]。如水蚤、蜜蜂、蒲公英和一些禾类中,这些现象为“天然单性生殖”,人为的刺激未受精卵发育,成为“人工单性生殖”,曾经实验过将蚕、青蛙、番茄等成功地进行单性生殖,可以完整地保留母体性状。
单性生殖的后代如果全为雄性,称为“产雄单性生殖”,例如蜜蜂产育雄蜂,就是一种产雄单性生殖;如果后代全为雌性,称为“产雌单性生殖”,例如夏季的蚜虫繁殖,新墨西哥鞭尾蜥的繁殖等。

Lettris
Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content. Each square carries a letter. To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares.
boggle
Boggle gives you 3 minutes to find as many words (3 letters or more) as you can in a grid of 16 letters. You can also try the grid of 16 letters. Letters must be adjacent and longer words score better. See if you can get into the grid Hall of Fame !
