Explanation:

1. The genotype of the organism is used to define its genetic constitution. To write down the genotype of an individual an alphabetic symbol is often assigned to it and then depending on whether the person is homozygous or heterozygous, his genotype is written down.

For e.g, If T is the allele for tallness and t for shortness and the person inherits both these alleles then his genotype would be Tt.

2. A person's phenotype refers to the external characters that are visible due to the particular genotype the person has. For eg., if a person inherits an allele for tallness then he has a phenotype of being tall.

3. A person is said to have a homozygous genotype if he carries the same allele for a given trait and is said to be heterozygous if he carries different alleles.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
