Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An organism’s appearance or some other detectable characteristic is it’s ____ ?
A
phenotype
B
gene
C
allele
D
genetic variation
Explanation: 

Detailed explanation-1: -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-2: -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-3: -Listen to pronunciation. (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: -A person’s genotype is their unique sequence of DNA. More specifically, this term is used to refer to the two alleles a person has inherited for a particular gene. Phenotype is the detectable expression of this genotype – a patient’s clinical presentation.

Detailed explanation-5: -With one locus and additive effects we have three phenotypic classes: AA, Aa and aa.
