Genetics of the Beautiful “Glass Gem” Corn
Corn gone viral? You’re looking at an ear of a corn variety called “Glass Gem”, grown by Greg Schoen of Seeds Trust. This is real corn! How does it grow this way?
First you have to understand a few things about corn. Each corn kernel is actually a sort of unique plant. A corn plant’s male parts (the “tassels”) sit at the top of the stalk, and drop pollen downward. Unfertilized ears (the female parts) catch the pollen with the sticky ends of their corn silks. Each corn silk (I hate when that gets in my teeth) grabs a pollen grain, shuttles it allllllll the way down inside the ear, eventually creating one kernel for each pollen-silk-ovum combination. It’s one of the more interesting and inefficient breeding schemes I know of.
If you’ve taken genetics, you know that the parents’ genes will combine by chance, leading to certain ratios of inheritance in the offspring. This is the basis of Mendelian genetics (great Khan Academy video here).
With corn, we’ve simply carefully bred all the interestingness out of them. Native Americans were used to multi-colored corn, because corn plants held many varieties of color genes that could combine at random. Now all we are left with are one-color clones.
This “Glass Gem” corn is the other extreme of the spectrum, a combination of corn color hybrid genes and random pollination. It’s almost too pretty to eat!

Anti-Latino Law In Arizona Causes Spike In Latino Absenses
A top U.S. Justice Department official warned Alabama’s education department that the state’s controversial immigration law has had “lasting” and possibly illegal consequences for Hispanic school children, according to a letter released Thursday.
“(The law has) diminished access to and quality of education for many of Alabama’s Hispanic children, resulted in missed school days, chilled or prevented the participation of parents in their children’s education, and transformed the climates of some schools into less safe and welcoming spaces for Hispanic children,” wrote Assistant Attorney General Thomas Perez, head of the federal department’s Civil Rights Division.
The legislation, known as HB 56, has several provisions, including one requiring police who make lawful traffic stops or arrests to try to determine the immigration status of anyone they suspect might be in the country illegally.
Superintendent of Education Thomas Bice points to data provided by Alabama officials that, he says, shows that “Hispanic students absence rates tripled while absence rates for other groups of students remained virtually flat.” That includes a sharp drop in those getting schooling through English as a second language programs, meaning they did not “receive the educational services to which they are legally entitled.”
