GENETICSEighteen months ago, plant researchers announced that Arabidopsis plants with mutated HOTHEAD genes had somehow given rise to progeny carrying a wild-type allele supposedly missing from both parents. But yesterday, in an online letter published by Nature , another team argued that undetected contamination may have "reintroduced" old versions of the HOTHEAD gene. ([Read more][1].)

Outcrossing as an Explanation of the Apparent Unconventional Genetic Behavior of Arabidopsis thaliana hth Mutants
TLDR
Results are confirmed and extended, corroborating that the apparent non-Mendelian behavior of hth mutants can be explained by their susceptibility to outcrossing.
