A gene is a portion ofDNAthat determines a trait. A trait is a characteristic, or a feature, passed from one generation to another, like height or eye color. Genes come in multiple forms or versions. Each of these forms is called an allele. For example, the gene responsible for the ha...
all compressed together to build you. When you were first made, you started out as a single cell that was formed by combining half of your dad's genetic material with half of your mom's genetic material. Therefore, you had two copies, or in other words two alleles, for each gene. ...
Comparing allele specific expression and local expression quantitative trait loci and the influence of gene expression on complex trait variation in cattle. BMC Genom. 2018, 19, 793. [CrossRef]
6c), an imprinted gene associated with the Prader-Willi and Angelman syndromes21. This haplotype exhibited statistically significant imbalances in both MML (MML-hap) and methylation entropy (NME-hap) between its two homologous alleles (allele 1: MML = 0.97 and NME = 0.21; allele 2: ...
Sequence variants in gene regulatory regions alter gene expression and contribute to phenotypes of individual cells and the whole organism, including disease susceptibility and progression. Single-nucleotide variants in enhancers or promoters may affect
Different alleles can be closely linked on chromosomes, unlinked on chromosomes or even be on different chromosomes and still influence expression of certain trait. Environment may also play a role in gene expression. Incomplete Dominance vs. Codominance ...
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 differ from each other? What are the differences of a genotype and a phenotype? What are ...
Taken together, these recent studies show that the causative SNP in Q vs q is the SNP in the miR172 target sequence. With the recent advances on the molecular characterization of Q, it becomes clear that Q has a relevance beyond the domestication history of wheat. It is also a gene with...
vary among individual organisms. Mendel showed that a cross of white- and purple-flowered pea plants didn't create a mixed color, but rather only purple- or white-flowered offspring. In this case, purple is a dominant trait, controlled by the purple-color allele for the flower color gene....
We found that the allele with the higher values of o occurred on the mat a chromosome for some of the genes and on the mat A chromosome for others, and this trait was gene-specific (Table 4). We also found that o values are o1 for mat a and mat A lineages for most of these ...
