The objective of this study was to estimate genetic parameters and to investigate the type of gene action in controlling androgenesis in wheat. Two wheat cultivars of Grebe and Houtman were reciprocally crossed with two synthetic genotypes of Do1 and Pol and then a complete set of the parents, F1, reciprocal F1 (RF1), F2 and back-cross generations (BC1 and BC2) of each cross were used for anthe...

A language evolves by modification and cultural inheritance. This legitimizes the attempt to reconstruct language history and describe the processes governing language evolution. The techniques developed in linguistics are also used in sequence analysis, where inheritance is genetic instead of cultural. These problems are exciting and hard. For sake of realism the project will entail major simp...

An extended family is described in which four sisters and half sisters presented with ectrodactyly. Two of the sisters had associated agenesis of the tibiae. The paper describes the malformations and discusses the management and possible genetic inheritance involved. An autosomal recessive gene seems likely to be the mode of inheritance.

A severely affected child born to consanguineous parents is interpreted as being a homozygote for the dominantly inherited piebald trait. The striking phenotypic difference between the parents and the child implies intermediate inheritance of this condition, and the family also illustrates that consanguinity should not always be taken to indicate genetic heterogeneity and recessive inheritance.

In genetic studies of complex diseases, the underlying mode of inheritance is often not known. Thus, the most powerful test or other optimal procedure for one model, e.g. recessive, may be quite inefficient if another model, e.g. dominant, describes the inheritance process. Rather than choose among the procedures that are optimal for a particular model, it is preferable to see a method that has...

Genetic variation and inheritance of randomly amplified polymorphic DNA (RAPD) markers in female grass carp (Ctenopharyngodon idella) and male bighead carp (Hypophthalmichthys nobilis) and their F1 offspring hybrid have been studied. For this purpose, genomic DNA was extracted from muscle tissue according to phenol-chloroform method, and six decamer primers were used for amplifying polymorphic ...

Genetic diversity among plants sprouted from seven year old clones of mulberry (Morus indica var. S36) was studied using molecular markers such as ISSR and RAPD. The clones showed significant variability in sex expression and the sprouting behavior. These changes were appeared after seven years of rigorous pruning and training (pruned once in every 3-4months). Genetic diversity analysis reveale...

objective: erroneous beliefs about causation and lack of adequate knowledge have been found to sustain deep seated negative attitudes about mental illness. conversely, better knowledge results in improved attitudes towards people with mental illness and a belief that mental illnesses are treatable can encourage early treatment seeking and promote better outcomes. the aim of this study was to as...
