How plants avoid incest: different versions of the same gene can be either dominant or recessive. A small non-coding RNA mediates such differences in dominance as part of a system that prevents inbreeding in plantsDaphne GoringEmily Indriolo
Each parent contributed one factor for each trait, and each trait came in one of two forms, dominant or recessive. Although only the dominant form would be visible in any combination of dominant and recessive, the recessive factor was still there, hidden, and could be passed to the next ...
The most common disease caused by mutations in POLG gene is adult-onset progressive external ophthalmoplegia (PEO), that could be a result of dominant or recessive mutation associated with single or multiple mtDNA deletions and often varying degrees of tissue-specific mtDNA depletion [120]. A ...
For example, the lamin A/C gene is expressed mostly in differentiated cells. People who inherit one mutated copy of the lamin A/C gene develop one of three different diseases: the autosomal dominant form of Emery-Dreifuss muscular dystrophy; dilated cardiomyopathy with conduction system disease; ...
Echolocation was a key development in toothed whale evolution, enabling their adaptation and diversification across various environments. Previous bioacoustic and morphological studies suggest that environmental pressures have influenced the evolution of
Single Gene Inheritance | Definition, Examples & Disorders from Chapter 3 / Lesson 3 54K Learn about single-gene inheritance. Study the single-gene trait definition, learn about dominant and recessive gene pairs, and see examples of single-gene traits. Related...
PHANTASTICA was the first gene found to be required for establishment of adaxial-abaxial polarity; when PHAN was mutated in Antirrhinum, the adaxial identity of leaves was lost and needle-like leaves were formed [5, 10]. Orthologs of PHAN have been reported in many species, such as ROUGH ...
Sex chromosomes in plants have often been contrasted with those in animals with the goal of identifying key differences that can be used to elucidate fundamental evolutionary properties. For example, the often homomorphic sex chromosomes in plants have been compared to the highly divergent systems in...
Do dominant alleles have a higher fitness (better survival rate) than recessive alleles? Does genetic drift or gene flow cause more unique phenotypes? How is genetic diversity important to the concept of natural selection? Do genetic mutations decrease d...
Epidermolysis bullosa simplex is a hereditary skin blistering disorder caused by mutations in the KRT5 or KRT14 genes. More than 50 different mutations have been described so far. These, and reports of other keratin gene mutations, have highlighted the existence of mutation “hotspots” in keratin ...
