Since identical twins occur as a result of the division of one egg, they have the same genetic structure. Therefore, their phenotypes and sex are also always the same. However, due to the effect of environmental factors, some of the characteristics of twins living in different regions appear to develop differently. In our case of 17-year-old maternal twins, we emphasized that nasal pathologies ...

Genetic diversity of fungal endophytes, Neotyphodium species, was studied in grasses Festuca arundinacea, F. pratensis and Lolium perenne using AFLP  markers. Fungi were isolated from the host leaf sheaths and Neotyphodium species were selected based on morphological characteristics. To confirm identity of selected fungi belonging to the genus Neotyphodium, polymerase chain reaction was perform...

in this study genetic diversity of eight iranian sheep breeds including; lori bakhtiari, makuei, moghani, taleshi, shal, zandi, naeini and kalakui was studied by using aflp method. a total of 309 individuals were analysed that produced 121 clear polymorphic bands. the average of heterozygosity within breed (hs) was high and equal to 0.2795± 0.0255. also, the average heterozygosity between breed...

iran is a part of the secondary centre of origin of melons, and therefore, there is a wealth of genetic variation of these species in this country. the amplified fragment length polymorphism (aflp) marker was applied to investigate the genetic variations among five major iranian melon cultigens (cucumis melo) and ‘ananasi’ as a general well-known cultivar. ten primer pairs were used on 90 indiv...

A total of 117 pomegranate genotypes collected from different areas of Yazd province of Iran were studied for genetic variation by evaluating 23 morphological traits according to the international descriptor. Similar diversity pattern of the measured characteristics was observed in three types of sweet, sweet-sour and sour varieties. The traits shape of fruit base, suckering tendency, vigor of ...
