Second Premolar Morphologic Trait Similarities in Twins

Journal of Dental Research, 1969
Seven morphologic traits of the mandibular second premolars were compared in 32 pairs of like-sexed twins to determine their value in diagnosing twin zygosity. Homolateral comparisons of the mandibular second premolars were accurate enough to be used as an aid in the diagnosis of monozygosity.

Morphological Traits of Entomophilous Flora

This chapter explores the multifaceted relationship between entomophilous flora and their primary pollinators, wild bees. It provides a comprehensive examination of the morphological traits employed by flowering plants to ensure successful pollination and reproduction.

Developmental patterns of human dental morphological traits

Archives of Oral Biology, 1982
A longitudinal series of casts of the deciduous and permanent dentitions of 827 children from Burlington Growth Centre study was examined for 5 traits: shovel-shape of the incisors, cusp six, cusp seven and protostylid of the mandibular molars, and Carabelli trait of the maxillary molars.

Morphological and Anatomical Traits of Halophytes

2020
The halophytes are plant species that have particular morpho-anatomical characteristics that allow them to complete their biological cycles in an environment that has very stringent conditions. In general, in these species, morpho-anatomical adaptations, or morpho-anatomical functional traits, are related to preventing the loss of water by ...

MAINTAINING THE DIVERGENCE OF MORPHOLOGICAL TRAITS IN DRY BEAN

Acta Horticulturae, 2007
Bean genotypes have been studied for divergence in three components of plant height and five direct yield components. The genotypes are part of the bean collection of Institute of Field and Vegetable Crops in Novi Sad and Bank of Plant Genes of Yugoslavia.

Measuring fitness heritability: Life history traits versus morphological traits in humans

American Journal of Physical Anthropology, 2017
AbstractObjectivesTraditional interpretation of Fisher's Fundamental Theorem of Natural Selection is that life history traits (LHT), which are closely related with fitness, show lower heritabilities, whereas morphological traits (MT) are less related with fitness and they are expected to show higher heritabilities.

Genetics of morphological trait expression

1997
Introduction McKusick's (1990) massive compendium Mendelian Inheritance in Man catalogs more than 12,000 autosomal dominant, autosomal recessive, and X-linked phenotypes, only 41 of which are dental variables. Fully one-third of these are developmental defects of the enamel and dentine, including several varieties of amelogenesis imperfecta.

Genetic architecture of trait variance in craniofacial morphology

GENETICS
Abstract The genetic architecture of trait variance has long been of interest in genetics and evolution. One of the earliest attempts to understand this architecture was presented in Lerner's Genetic Homeostasis (1954). Lerner proposed that heterozygotes should be better able to tolerate environmental perturbations because of functional ...

Morphological Traits of Two Seed-Feeding Beetle Species and the Relationship to Resource Traits

Neotropical Entomology, 2016
Morphological traits are useful to investigate insect sex-related differences in body size and to reveal differences in resource use. It has been suggested that as the resource increases, so does the body size of organisms interacting with the resource, highlighting the crucial role of resource quality and quantity in determining the morphological ...

The roughness of the supranasal region — a morphological sex trait

Forensic Science International, 2001
The supranasal region often attracts attention by a remarkable rough and jagged quality of the bony surface caused by an irregular supranasal suture and additional holes and pores. Some authors point out that there is a positive relation between the supranasal suture, the superciliar arches, and the forehead contour.
