Phenotype. An organism’s appearance or other detectable characteristic. Gene. One set of instructions on a strand of DNA for an inherited trait.
Which best defines phenotype?
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 the phenotype simple definition?
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.—
What is an example of phenotype?
Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.
What are the 3 types of phenotypes?
With one locus and additive effects we have three phenotypic classes: AA, Aa and aa.
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.
Why is phenotype important?
Phenotype matching is important, because it allows differential behavior toward previously unmet animals. Because phenotype matching nearly always employs information learned from relatives for discriminations, these behavioral decisions are consistent with kin selection.
What is phenotype and genotype with examples?
An organism’s genotype is the set of genes that it carries. An organism’s phenotype is all of its observable characteristics — which are influenced both by its genotype and by the environment. … For example, differences in the genotypes can produce different phenotypes.
