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

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.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
