What is a phenotype and genotype?
The predominant current-day meaning of genotype is some relevant part of the DNA passed to the organism by its parents. The phenotype is the physical and behavioral traits of the organism, for example, size and shape, metabolic activities, and patterns of movement.
What is genotype and phenotype explain with example?
The genotype is a set of genes in DNA responsible for unique trait or characteristics while the phenotype is the physical appearance or characteristic of an organism.
What is a genotype simple definition?
In a broad sense, the term “genotype” refers to the genetic makeup of an organism; in other words, it describes an organism’s complete set of genes. In a more narrow sense, the term can be used to refer to the alleles, or variant forms of a gene, that are carried by an organism.
How many phenotypes are there?
There are three common alleles in the ABO system. These alleles segregate and assort into six genotypes, as shown in Table 1. As Table 1 indicates, only four phenotypes result from the six possible ABO genotypes.
What is phenotype expression?
Phenotypic expression is the result of a complex interplay between an organism’s genes and its environment. During growth and development, organisms undergo a programmed series of phenotypic changes. Phenotypic expression thus varies throughout growth and development, even when the environment in homogenous and static.
Which are phenotypes?
Phenotype refers to an individual’s observable traits, such as height, eye color and blood type. A person’s phenotype is determined by both their genomic makeup (genotype) and environmental factors.
What is the best definition of phenotype?
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.—
