Answer:
Genotype is the set of genes( allele) of an organism.
Phenotype is the physical expression of the genetic composition of an organism.
Explanation:
Genotype: 1. It is the genetic composition of an organism, means it is the set of genes( allels) of an organism's DNA, which is responsible for a particular trait of an organism.
2. Genotypically, an organism can be homozygous(dominant or recessive) or heterozygous. Some Alleles are dominant over other, means some can be dominant or other can be recessive.
3. Genes are responsible for all the traits in an organism, and these traits are inheritable. All the offsprings inherit all traits from their parents.
Phenotype: 1. Physical expression of the genetic composition of an organism resulted as phenotype.
2. It is the physical expression of genes (alleles) which are responsible for any trait.
The relationship between genotype and phenotype is that the genotype is the genetic information that governs the phenotype in principle.
- Each individual has a unique and unrepeatable expression of the genome, that is, a total genetic information of their organism, which is called genotype.
- This genotype is materialized in a series of physical and perceptible characteristics, which form the phenotype.
- The phenotype of any individual is thus determined by the unique genetic makeup that its DNA contains, so that different genotypes produce different phenotypes.
- That is the reason why two children of the same mother and the same father can be so physically different from each other.
Therefore, we can conclude that genotype is a unique configuration of genes in DNA within cells, while phenotype is the way that information is expressed.
