Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The physical expression of a trait in an organism is known as the-
A
chromosome
B
genotype
C
phenotype
D
double helix
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -Phenotype 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.

Detailed explanation-3: -(FEE-noh-tipe) The observable characteristics in an individual resulting from the expression of genes; the clinical presentation of an individual with a particular genotype.

Detailed explanation-4: -The physical expression of a gene is called the phenotype.

Detailed explanation-5: -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.
