STERILE VARIANTS of Morning Glories are quite common, and the Japanese people of the Edo Period propagated them with an intuitive or empirical estimation of Mendel's Laws, although not articulated as such. Normal appearing (recessive) plants with related genes will give rise to progeny with both normal phenotype and the variant. View in LinkedIn

FOUR NEW VARIEGATION GENES in Morning Glory flowers. https://lnkd.in/d7T-EmR View in LinkedIn

SPECKED MORNING GLORIES CONTROLLED BY 2 GENETIC ELEMENTS. "The appearance of the variegation phenotypes in the speckled mutant was controlled not only by the recessive speckled allele but also by a dominant genetic element, termed speckled-activator...the recessive c-1 mutation affecting pigmentation of flowers and mapped near the speckled locus causes a defect in a regulatory gene controlling the expression of structural genes for anthocyanin biosynthesis." https://lnkd.in/dm7F8hH View in LinkedIn

MORNING GLORY PHENOTYPES. "It is possible to associate discrete floral phenotypes with individual genes. An important finding is that almost all of the mutations that determine phenotypic differences are the result of transposon insertions. Thus, the flower color diversity...of this plant is a consequence of the rich variety of mobile elements that reside in the morning glory genome." https://lnkd.in/dUZYMwf View in LinkedIn

JUMPING GENE INSERTIONS IN MORNING GLORIES. "Most of these spontaneous mutations were found to be caused by the insertion of DNA transposable elements in the genes for the anthocyanin pigmentation in flowers." https://lnkd.in/dcJc-gp View in LinkedIn

"SPECKLED WHITE AND BLUE Morning Glory variants occur when a transposons has disrupted the blue pigment gene. In the native deep blue bell, the transposons is not active or not present. These transposons can jump around the DNA affecting both shape and color." https://lnkd.in/d7HNP37 View in LinkedIn

COMPOUND CLUES. "Sometimes a feature’s function (if it ever had one) can be lost or shifted, but compound clues together reveal the intertwined relationship between a lineage’s phylogeny and ontogeny." https://evolution-outreach.springeropen.com/articles/10.1186/s12052-014-0012-5 View in LinkedIn

HOLDOVER NAVEL. "Perhaps the most conspicuous ontogenetic leftover is found on the abdomen of all placental mammals: the umbilicus (navel or ‘belly button’). Strictly speaking this is a scar: although the umbilical cord has a function, the umbilicus itself never had one, making this a nonfunctional embryonic holdover, unlike the formerly functional circulatory and urogenital remains." https://evolution-outreach.springeropen.com/articles/10.1186/s12052-014-0012-5 View in LinkedIn

POSTNATAL TAILS. "All chordates possess, again at some stage of the life cycle, a postanal tail. Because the tail is retained in many ‘adult’ (i.e., sexually mature) chordates—and in nearly all adult vertebrates, with the major exception of apes and frogs—this can often be viewed as a true evolutionary vestige when the tail is partly or wholly non-functional in adults." https://evolution-outreach.springeropen.com/articles/10.1186/s12052-014-0012-5 View in LinkedIn
