Why is the frequency of the occurrence of heterozygous genotype 2pq? Statistically, it should be pq, since the possibility that an organism has a dominant allele and a recessive allele is p (the freq How to calculate phenotype and genotype ratios. ...
Phenotype Is an autosomal recessive trait heterozygous? How to calculate allele frequency in a population? Show the possible genotypes and phenotypes of the offspring from a cross between a heterozygous male with type A blood and a heterozygous female with type B blood. What is the Punnett square...
It is remarkable that the ultimate change in trait mean, which may take the phenotype far beyond its initial range, can be predicted simply from the components of variation in the original population. Epistatic variance makes a bigger contribution to the ultimate response of a diploid population:...
In this study, we applied this approach to a large number of mtDNA sequences from patients with cardiomyopathy or another potential mitochondrial disease phenotype. These patient sequences were compared with thousands of mtDNA sequences using our automated analysis system, MITOMASTER. The approach ...
Challenges aim to test whether certain problems can be addressed with existing tools and to find out what kind of methods will be needed in the future. Critical Assessment of Structure Predictions (CASP) [6] was the first challenge of this kind in biosciences. The idea was, and still is,...
These studies include evaluation of single-nucleotide polymorphisms (SNPs) or deletions and determination of their association with a disease phenotype. Diseases studied range from Inflammatory Bowel Disease (IDB) to schizophrenia [104,105]. Until recently, most GWAS studies focused on protein-coding ...
Summarizing, even in conditions that strongly favored the virus to adapt to the proteasome and TAP, we find no massive adaptation to these monomorphic molecules. Under all conditions tested, the majority of the adaptations in the virus were escape mutations that affected the MHC-binding filter. Di...
A primary characteristic of complex diseases is that they are likely to aggregate in families (that is, familial aggregation, also referred to as recurrence risk or lambda, λ). The aggregation of a phenotype is observed when a disease occurs at a higher frequency in the relatives of an affec...

Transcriptional bursting has been linked to the stochastic positioning of nucleosomes. However, how bursting is regulated by the remodeling of promoter nucleosomes is unknown. Here, we use single-molecule live-cell imaging of GAL10 transcription in Sacch
