Erika has taught college Biology, Microbiology, and Environmental Science. She has a PhD in Science Education. Some physical traits are not determined by a simple pattern of inheritance. For example, height and skin color are caused by additive alleles. This lesson will explain how additive allele...
In future, this knowledge may give clinicians more insight into the disease and change the definition of some disorders. References Adan RAH, Vink T (2001) Drug target discovery by pharmacogenet- ics: mutation in the melanocortin system and eating disorders. Eur Neuropsychopharmacol 11:483–490 ...
First, the S-locus in the Solanaceae, by definition, is always expressed in heterozygous condi- tion, as pollen is rejected if it bears either allele held by the maternal plant. Second, the S-locus is in a non- recombining region of the genome (Coleman and Kao, 1992). Therefore, ...

Gregor Mendelonly studied traits in his pea plants that showed simple or complete dominance and had only two alleles that could contribute to any one trait the plant showed. It wasn't until later that it was discovered that some traits can have more than two alleles that code for their phen...
In wheat, the vernalization requirement is mainly controlled by the VRN genes. Different species of hexaploid and tetraploid wheat are widely used as genetic source for new mutant variants and alleles for fundamental investigations and practical breeding
Adopting a definition of NLR clusters as genes within 200 kb of each other in the genome (Holub, 2001), 47%–71% of NLR genes in each accession were located in such clusters. A particularly interesting subset of NLR genes are those in head-to-head orientation, termed paired NLRs (Narusa...
This definition of the expected fitness of the double mutant is appropriately modeled by a single linear mixed-effects model. This allows us to model the growth rates of each colony of the four genotypes (WT, i, j, ij) using two categorical variables. The only assumption of the model is ...
(Uyenoyama, 1997a). Lineage-specific load refers to deleterious recessive mutations associated with particular alleles at the S-locus, and is expected to accumulate due to two factors. First, the S-locus in the Solanaceae, by definition, is always expressed in heterozygous condition, as pollen ...
