aThe genotype of an individual is its specific genetic encoding; in the case of species that reproduce sexually,the genotype of an individual is entirely determined by that of its parents, each of whom contribute half of their own genotype to the offspring. 个体的基因型是它的specific基因...
Type of pathogen A number of fungal, bacterial and viral pathogens is responsible for causing respiratory infections by utilising aerosolised modes of transmission (see Table 2). The size of these pathogens may firstly dictate the size of the particle carrying the pathogen. For example, larger pa...
An example of dominant allele expression is flower color in pea plants. A plant with purple flowers actually has a genotype (genetic makeup) consisting of a gene with a dominant P and a recessive p allele.DiscoverWhy Is It Called Black Friday? Why do frozen turkeys explode when deep-fried...
The genotype for the height of an organism is 'Tt'. What conclusion can be drawn from this? The allele for height has at least two different genes. There are at least two different alleles for the gene controlling height. There is one allele for height with two different forms. The...
Sex differences exist in many neurological and psychiatric diseases, but these have not always been addressed adequately in research. In order to address this, it is necessary to consider how sex is incorporated into the design (e.g. using a balanced des

Amphibians have highly diverse sex-determining modes leading to a notable interest in vertebrate sex determination and sex chromosome evolution. The identification of sex-determining systems in amphibians, however, is often difficult as a vast majority c
The incriminated food, however, was more difficult to identify (cucumbers, tomatoes, and salads were suspected, although seeds were finally the contaminated agents), as well as the reason and process that had led to such a contamination. This example shows the power of whole genome sequencing ...

Previous studies on norovirus mutation rate within the VP1 gene from 64 unique molecular clones have estimated a mutation rate of 1.5 × 10−4 per nucleotide per cell infection [8]. In Thailand between 2000 and 2016, genogroup GII.4 was the most prevalent norovirus genotype (63.4%) in...
