When both alleles are the same the individual is described as being a HOMOZYGOTE; when each allele is different the individual is a HETEROZYGOTE. The number of allelic forms of a gene can be many (MULTIPLE ALLELISM), each form having a slightly different sequence of DNA bases but with the ...
aIf the DNA sequence at a locus varies between individuals, the different forms of this sequence are called alleles. 如果脱氧核糖核酸序列在所在地变化在个体之间,这个序列的不同的形式称等位基因。 [translate] 英语翻译 日语翻译 韩语翻译 德语翻译 法语翻译 俄语翻译 阿拉伯语翻译 西班牙语翻译 葡萄牙语翻译...
The ladder-like structure of DNA usually twists to the right. This twist makes DNA’s shape asymmetrical. If you try to superimpose the mirror image of DNA onto itself, it will not fit. Just like your right and left hand. There are forms of DNA that have been discovered to have other...
Alleles come in a variety of forms. The most prevalent or typical allele in nature that encodes the typical or standard form of a trait is known as a wild-type allele. Alleles that have suffered a change or mutation in their DNA sequence and produced a different version of the trait are ...
Promoter DNA methylation can be spontaneously reverted leading to different epialleles affecting VTE3(1) expression and VTE content in fruits. These findings indicate therefore that naturally occurring epialleles are responsible for regulation of a nutritionally important metabolic QTL and provide direct ...
What are the different forms of a gene called? They could be dominant or recessive. Explain the difference between a dominant gene and a recessive gene. What is the genotype of a trait for which the two alleles an individual carries diffe...
The presence of multiple allelic forms might reduce the selection pressure on the pathogen, thereby increasing the durability of resistance5. In addition, intragenic pyramiding that combines the specificities of different alleles is an alternative to broaden the recognition spectrum as compared to the ...
The latter study also showed a different frequency of the repeats between the northern and southern European populations [12]. The comparison of different studies on the effects of interme- diate-length alleles is complicated by the varying inter- mediate-length allele thresholds. The different ...
In addition, allelic variation in Wx and other starch synthesis-related genes results in different grain appearance and physicochemical properties [10], [36], [37], [38]. Thus, we examined the uncovered possible roles of FLO2 and assessed allelic effects of flo2 on the expression of starch ...
Ge- netic polymorphisms may also be factors susceptible to some forms of male infertility, albeit somewhat contro- versially, e.g., whether the CAG repeat of the human androgen-receptor gene is linked to male infertility (Dowsing et al. 1999). Defective meiosis during spermatogenesis is one ...
