    The goal of the University of Florida's Retrospective Dissertation Scanning project is to build a digital collection of approximately 8, dissertations written by PhD graduates of the University of Florida from This page is the portal to the UF dissertations scanned and made available via the Internet Archive up to this point.   This larval color polyphenism is unrelated to the genetic polymorphism for melanic phenotypes in adult moths. B. betularia caterpillars are generalist feeders and develop body colors that closely match the brown or green twigs of their host plant.

    This book facilitates an integrative understanding of the development, genetics and evolution of butterfly wing patterns. To develop a deep and realistic understanding of the diversity and. Abstract. The genetic basis of color polymorphism is explored in the pea aphid, Acyrthosiphon pisum (Harris) (Homoptera: Sternorrhyncha), in which two color morphs have been described (pink or green). Laboratory crosses and a Mendelian genetic analysis reveal that color polymorphism in pea aphids is determined by a single biallelic locus, which we name colorama, with alleles P and p, pink.

    In biology and zoology, polymorphism is the occurrence of two or more clearly different morphs or forms, also referred to as alternative phenotypes, in the population of a species. To be classified as such, morphs must occupy the same habitat at the same time and belong to a panmictic population (one with random mating).. Put simply, polymorphism is when there are two or more possibilities of.   Is colour polymorphism common? Colour polymorphism occurs across a breadth of taxa and ecological contexts. Cases are documented for most major metazoan animal groups (), across gymnosperm and angiosperm plants, and for species residing in terrestrial and aquatic animals, the incidence of colour polymorphism appears over-represented (if not over-reported) in .

Only larval diet influenced morph induction, since all caterpillars reared on catkins developed into the catkin morph, and all caterpillars reared on oak leaves developed into the twig morph, regardless of whether they perceived yellow light, green light, or were raised in the dark.

Abstract. Caterpillars of the hawkmoth Eumorpha fasciata are highly polymorphic for colour, with green, pink, and pink-and-yellow forms in the second through fourth instars, and green and multicoloured forms in the fifth instar. Four years of field censuses on four foodplant species determined that all morphs were found on all plant species; morph frequencies were homogeneous on each plant.

The study of polymorphisms is particularly informative for enhancing our understanding of phenotypic and genetic diversity. The persistence of polymorphism in a population is generally explained by balancing selection. Color polymorphisms that are often found in many insects and arthropods are prime examples of the maintenance of polymorphisms via balancing selection.

Caterpillars of the hawkmoth Eumorpha fasciata are highly polymorphic for colour, with green, pink, and pink-and-yellow forms in the second through fourth instars, and green and multicoloured.

The candidate color pattern locus extends from the first coding exon of the ortholog of the Drosophila gene pannier, including its first intron and first non-coding exon, to the end of the neighboring 5′ gene, the GATAe ortholog (Figure 1D).

To test a possible role of pannier or GATAe in adult color pattern formation, we used RNA interference (RNAi) []. This polymorphism is seen in Papilio dardanus, the African swallowtail butterfly, whose females have three different morphs for wing color pattern: a black-and-white pattern for Batesian mimicry, a black-and-yellow pattern that resembles the males of the species, and a pattern with orange patches that resembles the elderly males of the species.

Pannier is necessary to produce black pigment, and its expression pattern prefigures the coloration pattern in each color form. This larval color polyphenism is unrelated to the genetic polymorphism for melanic phenotypes in adult moths.

The mottled rock rattlesnake (Crotalus lepidus lepidus) is a montane species that exhibits among-population color polymorphism that correlates with substrate color. Habitat substrate in the eastern part of its range is composed primarily of light colored limestone and snakes have light dorsal coloration, whereas in the western region the.

Polymorphism, in crystallography, the condition in which a solid chemical compound exists in more than one crystalline form; the forms differ somewhat in physical and, sometimes, chemical properties, although their solutions and vapours are identical.

The existence of different crystalline or molecular forms of elements is called allotropy, although it has been suggested that the meaning of.

Flower color of B. davidii was determined using the Royal Horticultural Society Color Chart and ranged from purple to white.

Volume of nectar produced by a single flower ranged from μl to μl and total sugar. Thus, opsins provide an excellent model system to study evolutionary interconnections at genetic, phenotypic, and behavioral levels.

Primates have evolved a unique ability for three-dimensional color vision (trichromacy) from the two-dimensional color vision (dichromacy) present in .Sphingid caterpillars are medium to large in size, with stout bodies.

They have five pairs of prolegs. Usually, their bodies lack any hairs or tubercules, but most species have a "horn" at the posterior end, which may be reduced to a button, or absent, in the final instar. Many are cryptic greens and browns, and have countershading patterns to conceal them.General Chromosomal polymorphism.

InM. J. D. White, then at the end of a long career investigating karyotypes, gave an interesting summary of the distribution of chromosome polymorphism. "It is extremely difficult to get an adequate idea as to what fraction of the species of eukaryote organisms actually are polymorphic for structural rearrangements of the chromosomes.
