Variation
The differences in the characters or traits among the individuals of the same species and the offspring of the same parents
Heredity
The process of transmission of genetic traits/characters from one generation to another i.e from parents to offsprings
Gene
Functional unit of heredity present at a specific point on a chromosome
Genome
The total number of genes present in the haploid set of chromosomes or gametes
Progeny
The offsprings produced by mating
Factors
Genes located on the chromosome.
Alleles
Two alternative forms of a unit factor
Dominant alleles
Expressed in both heterozygous and homozygous conditions
Recessive alleles
Expressed in homozygous conditions only
Genotype
The specific genetic composition of an organism
Phenotype
The observable characters or physical appearances of an organism that are genetically controlled
Principal of paired factors
Genetic characters are controlled by a pair of unit factors or genes , one inherited from each parent
Principle of dominance
In a single individual when 2 alleles of a single unit factor are present one allele is dominant over other
Law of segregation
The paired alleles
