With the aid of high resolution chromosome banding, a t(3;20) translocation was discovered in a large family with six retarded members. The translocation involved very small terminal segments. The unbalanced products resulting in partial trisomy 20q and monosomy 3p were observed in the retarded subjects. Gene localisation studies of the ADA gene, with a presumed locus on the long arm of chromos...

In order to estimate the number and inheritance of controlling genes for grain yield and some of the related traits in barley, Afzal and Radical varieties along with their F1, F2 and F3 generations were planted in a randomized complete block design with three replications. Head weight, head length, number of heads, number of spikelets, awn length, hundred grain weight, grains per head, straw yi...

BACKGROUND The entomopathogenic mushroom Cordyceps militaris is an important medicinal and food resource owing to its various medicinal components and pharmacological effects. However, the high frequency of strain degeneration during subculture seriously restricts the large-scale production of C. militaris, and the mechanism underlying strain degeneration remains unclear. In this study, we arti...

The harmful effects of inbreeding can be reduced if deleterious recessive alleles were removed (purged) by selection against homozygotes in earlier generations. If only a few generations are involved, purging is due almost entirely to recessive alleles that reduce fitness to near zero. In this case the amount of purging and allele frequency change can be inferred approximately from pedigree dat...

The purpose of breeding is to improve the quantity and quality of the desired characteristics in cultured species in the next generations. Individual selection is a simple and practical way to provide a quick response in improving high heritability traits for breeding most species in aquaculture. At first step, in Yasouj cold water fishes breeding research Center, in order to conducting selecti...

Today’s market includes a penetrating segment commonly known as Generation X. This controversially complex cohort promises to give marketers a run for their money. Disagreement surrounding the segment is vast, encompassing everything from attitudes to more complex issues of their consumer attributes. Are they self-centered, demanding brats or savvy, welleducated individuals? In general, Generat...

This article reports key findings from the first phase of a research project investigating Net generation age students as they encounter e-learning at five universities in England. We take a critical view of the idea of a distinct generation which has been described using various terms including Net generation and Digital Natives and explore age related differences amongst first year university...

White sponge naevus occurred in association with coloboma of the iris in six members of one family, across three generations. The association of these two dominantly inherited conditions has not to our knowledge previously been described.

Inheritance of physiologicaly related salt tolerance traits including Na+ and K+ contents, K+/Na+ ratio of young leaves and biological yield (BY) in six basic generations (P1, P2, F1, F2, Bc1 and Bc2) and their reciprocal crosses derived from crosses between Kharchia × Niknejad and Shorawaki × Niknejad were studied in sand culture under high salinity treatment (EC = 22.5 dS m-1). Generation mea...
