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” [35].
What are the 3 types of phenotypes?
With one locus and additive effects we have three phenotypic classes:
AA, Aa and aa
.
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.
What is a phenotype quizlet?
Phenotype.
An organism’s appearance or other detectable characteristic
.
Gene
.
One set of instructions on
a strand of DNA for an inherited trait.
What is a simple definition of phenotype?
A phenotype is
an individual’s observable traits, such as height, eye color, and blood type
. The genetic contribution to the phenotype is called the genotype. Some traits are largely determined by the genotype, while other traits are largely determined by environmental factors.
What is difference between genotype and phenotype?
The sum of an organism’s observable characteristics is their phenotype. A key difference between phenotype and genotype is that,
whilst genotype is inherited from an organism’s parents, the phenotype is not
. Whilst a phenotype is influenced the genotype, genotype does not equal phenotype.
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 synonym for phenotype?
phenotype, constitution,
composition
, physical composition, makeup, make-up.
What is an example of genotype and phenotype?
For example,
two mice that look virtually identical
could have different genotypes. But if they have visibly different traits – say, one has white fur and the other has black fur – then they have different phenotypes.
Is PP genotype or phenotype?
A simple example to illustrate genotype as distinct from phenotype is the flower colour in pea plants (see Gregor Mendel). There are three available genotypes, PP (
homozygous dominant
), Pp (heterozygous), and pp (homozygous recessive).
What is the relationship between phenotype and genotype quizlet?
Terms in this set (15)
a phenotype i the
physical expression
of the genotype. The genotype is the combination of alleles rom one or more genes.
What is a phenotype Quizizz?
The physical appearance of an organism based on traits
. Genotype. 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.
