ankyloglossia (tongue-tie) is a congenital anomaly with a prevalence of 4-5% and characterized by an abnormally short lingual frenulum. for unknown reasons the abnormality seems to be more common in males. the pathogenesis of ankyloglossia is not known. the authors report a family with isolated ankyloglossia inherited as an autosomal dominant or recessive trait. the identification of the defect...

We study, in this paper, curvature inheritance symmetry (CI), £ξR a bcd = 2αR bcd , where α is a scalar function, for string cloud and string fluid in the context of general relativity. Also, we have obtained some result when a proper CI (i.e., α 6= 0) is also a conformal Killing vector.

Background and Aims: Retinitis pigmentosa (RP) is the most common form of inherited retinal degeneration, photoreceptors loss of which in the retina causes visual loss. The purpose of the present study was to determine patterns of inheritance in RP patients in Yazd to help the health professional for designing suitable laboratory testing for the high risk families. Materials and Methods: Thirt...

The resolution of a paternity case is presented in which two indirect exclusions were found for the alleged father during routine paternity testing. Genetic studies on family members of the alleged father elucidated the inheritance pattern within the phosphoglucomutase (PGM1) and Duffy (Fy) blood group systems.

Many of our most common diseases are complex disorders, run in families, but they lack the simple inheritance patterns characteristics of single gene disorders. Complex diseases have low heritability compared to single gene disorders. Understanding the genetic factors underlying common disorders is a difficult but critical task because each genetic and environmental factor can contribute toward...

In diploid organisms each body cell (or 'somatic cell') contains two copies of the genome. So each somatic cell contains two copies of each chromosome, and two copies of each gene. The exceptions to this rule are the sex chromosomes that determine sex in a given species. For example, in the XY system that is found in most mammals including human beings males have one X chromosome and one Y chro...

Heritable Variation Heredity is the transmission of traits from one generation to the next. Gregor Mendel worked in the 1860s Was the first person to analyze patterns of inheritance Deduced the fundamental principles of genetics Mendel studied garden peas because they are easy to grow Come in many readily distinguishable varieties Are easily manipulated Can self-fertilize A character is a herit...
