Explain the relationship between genotype and phenotype. How can one phenotype result from more than one genotype?
koban [17]

Answer:

<h2>Genotype is the set of genes( allele) of an organism. </h2><h2>Phenotype is the physical expression of the genetic composition of an organism. </h2>

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.
