Today is the 14th day of growing and usually by now most of the plants are flowering.  Hmmmm, I wander if the plants are putting so much energy into producing hairs that they have to slow down other processes?  They certainly looked like hairier plants but honestly I forgot how hairy the first generation was.<\/p>\n<p>Here&#8217;s what the plants looked like today.  They not only seem to be a bit behind but they also seem to have quite a bit more plants that haven&#8217;t quite developed right.  Of course, this population comes from a pretty small parent population so we may already be seeing sign of inbreeding depression&#8212;hmmm, sounds like an experiment.<\/p>\n<p><a href=\"https:\/\/www.flickr.com\/photos\/24717442@N07\/13896251518\" title=\"photo (19) by Brad Williamson, on Flickr\"><img decoding=\"async\" src=\"https:\/\/farm3.staticflickr.com\/2900\/13896251518_0e0292f47a_b.jpg\" width=\"1024\" height=\"768\" alt=\"photo (19)\"><\/a><\/p>\n<p>And now for the results (just in graph form) for now.  I may follow-up with more analysis later.  The error bars on the bar graph represent 2 standard errors and thus serve to approximate 95% confidence intervals.  Note that both distributions approximate a normal distribution so we would be safe to use parametric descriptive and inferential statistics.<\/p>\n<p><a href=\"https:\/\/www.flickr.com\/photos\/24717442@N07\/13896179778\" title=\"Screen Shot 2014-05-01 at 12.45.57 PM by Brad Williamson, on Flickr\"><img decoding=\"async\" src=\"https:\/\/farm3.staticflickr.com\/2903\/13896179778_61db4a1ba5_b.jpg\" width=\"1024\" height=\"593\" alt=\"Screen Shot 2014-05-01 at 12.45.57 PM\"><\/a><\/p>\n<p>I&#8217;m not putting forth any conclusions right now but you are welcome to.  <\/p>\n<p>BW<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Last Fall I completed the first round of an artificial selection experiment using Fastplants similar to one described in the new AP Biology Lab manual.\u00a0 I finally got around to planted, growing and scoring the second generation of seeds selected for higher trichome numbers.
