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: -(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-3: -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-4: -Physical appearance resulting from genotype is called phenotype. The phenotype is what you observe from the genes expressing themselves. For example, if you see that your eyes are brown, you have genes that express the color brown for your eyes.
