What is Genotype?

• Thegenetic composition of an organism is known as the genotype of that organism.

There are two alleles for the genes of height in an organism: Tall and dwarf.

The tallness is represented as capital T where as the dwarfness is represented as small t.

If both the alleles are present in an organism, the genotype composition is known as heterozygous.

Whenonly one type of allele is present in an organism the genotype composition is known as homozygous.

What is Alleles?

• Alleles areare one pair of a gene which appears on a particular location on the chromosome and controls the same type of the characteristic.

What is genes?

• Genes are the unit of deoxyribonucleic acid or DNA present on chromosome and governs the synthesis of a protein which controls a specific characteristics of the organism.
