1 : the observable characteristics or traits of an organism that are produced by the interaction of the genotype and the environment : the physical expression of one or more genes Considering that modern maize is a tetraploid, it is remarkable how many single gene mutations cause profound changes in phenotype.—
How do you describe a phenotype?
The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. An organism’s phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.
What is phenotype best described as?
The phenotype is best defined as the “observable characteristics that result from the expression of genes of an organism, which can largely be modulated by environmental or other conditions” .
What is phenotype in your own words?
Phenotype refers to the observable characteristics of an organism as a multifactorial consequence of genetic traits and environmental influences. The organism phenotype includes its morphological, biochemical, physiological, and behavioral properties.
Which description is an example of phenotype?
A phenotype results from gene expression and the physical factors of their environment. For example, tree height in many Mangrove species is controlled by environmental stressors such as temperature and drought; thus, tree height in mangroves is a phenotype.
Are blue eyes a phenotype?
Finally, the genotype of an organism with two recessive alleles is called homozygous recessive. In the eye color example, this genotype is written bb. Of these three genotypes, only bb, the homozygous recessive genotype, will produce a phenotype of blue eyes.
What are the 3 types of phenotypes?
With one locus and additive effects we have three phenotypic classes: AA, Aa and aa.
What are 3 examples of phenotypes?
- Eye color.
- Hair color.
- Sound of your voice.
- Certain types of disease.
- Size of a bird’s beak.
- Length of a fox’s tail.
- Color of the stripes on a cat.
Is Behaviour a phenotype?
A behavioural phenotype refers to observable characteristics that occur more often in individuals with a specific genetic syndrome than individuals without that syndrome. Whilst a behavioural phenotype describes observable behaviour, the term ‘endophenotype’ describes characteristics that are not directly observable.
Is skin color a phenotype?
Skin color variation is one of the most striking examples of human phenotypic diversity. It is dominated by melanin, a pigmentation located in the base of the epidermis and produced by melanocytes. Melanin has two forms, pheomelanin (yellow-reddish) and eumelanin (black-brown).
What is a phenotype in layman’s terms?
The phenotype of an organism is the whole set of characters (or traits) of that organism. It does not mean just ‘what you can see on the surface’. Rather, it means anything which can be made visible by suitable means. For example, blood groups are definitely a part of the phenotype.
