the mode of inheritance of seedling color and plant pubescence was studied in two crosses among three parents, which differed for these traits. the results have revealed that purple seedling color was dominant over green seedling color and pubescence was dominant over nonpubescence. these two traits segregated independently of each other may be used as morphological markers individually for dif...

lamellar ichthyosis is one form of congenital autosomal recessive ichthyosis. to date, seven causative genes for arci have been identified. to understand further the genetic spectrum of the disease, we analyzed a four-generation iranian family with arci that had observable inheritance. exome sequencing data for one of the affected individuals with ichthyosis from a consanguineous iranian family...

in order to increase drought tolerance in bread wheat, an appropriate breeding program based on inheritance of drought tolerance is recommended. in the present study, nine bread wheat cultivars and their f2 progenies were evaluated in a randomized complete block design under normal and drought stress conditions. nine sensitivity/tolerance indices were calculated for studied genotypes and stress...

We propose, and test using a Monte-Carlo analysis (a computer-based numerical analysis using a random number generator), a novel and efficient method to obtain sets of DNA markers linked to any inherited genetic locus. The method consists of a targeted search that is based on the common inheritance among members of an outbred pedigree, of discrete chromosome lengths, which we call inheritance u...

abstract background: it is well recognized that different patients respond in different ways to medications. the inter-individual variations are greater than the intera- individual variations, a finding consistent with the notion that inheritance is a determinant of drug responses. the recent identification of genetic polymorphisms in drug-metabolizing enzymes and drug transporters led to the h...

investigation of inheritance, mode of gene action and determination of effective breeding strategy for improvement of physiological and morpho-physiological traits specifically in drought stress conditions is very important. to determine the inheritance pattern and genetic parameters of quantitative characters in bread wheat (triticum aestivum), p1, p2, bc1, bc2, f1, f2 generations derived from...

Causation of a disease and a symptom generally is classified as genetic inheritance and environmental factors. A disease caused by a single gene disorder is defined as a disease that is attributed to a monogenic factor. A single gene disorder has been reported in more than 3,000 hereditary diseases. On the other hand, a polygenic or multifactorial disease is attributed to some susceptibility ge...

In species where males provide neither direct benefits nor paternal care, it is typically assumed that female preferences are maintained by indirect selection reflecting genetic benefits to offspring of preferred males. However, it remains unclear whether populations harbour sufficient genetic variation in fitness to support costly female preferences - a problem called the 'lek paradox'. Here, ...

BACKGROUND The mechanism that initiates the onset of puberty is largely unknown but the age of onset is mainly under genetic control and influenced by environmental factors including nutrition. Familial forms of constitutional delay of puberty (CDP) suggest the involvement of genetic factors. The purpose of this study is to describe the presentation and the mode of inheritance of CDP in a serie...
