Hint: Genotype and phenotype terms may sound similar, but there is a huge difference between genotype and phenotype. The genotype is a set of genes in DNA that are responsible for unique traits or characteristics, while the phenotype is the physical appearance or characteristics of the organism.

Complete answer:
The genotype of the human genetic code could be found. It sets out the characteristics that will be expressed. Organisms that look the same do not have the same genotype. Genotypes can be determined by biological tests.

The phenotype is determined by the individual's genotype and expressed genes or by the visible trait, e.g. hair color or type, eye color, body shape and height. It depends on the genotype, but also on environmental factors.

Genotype and phenotype are two different concepts, but they are closely related to each other. Phenotype refers to the physical traits that are observed in an organism that are the result of an individual's gene expression. The genotype determines the individual's phenotype.

The different types of genotypes are homozygous recessive (pp), homozygous dominant (PP) and heterozygous (Pp). The homozygous dominant and heterozygous genotypes show the same phenotypes. Alleles are variants of genes, while the gene set responsible for certain traits is known as genotypes. Both, however, determine biological traits, but copies may not be the same.

Note: The genotype of the individual is influenced by the environmental factors in which the organism lives or by the internal body environment of the organism, such as hormones and metabolism.A genotype can be identified with a Punnett square. It helps to determine the probability of a parent genotype based on the parent genotype.
