Gene- it is the unit of inheritance which control a trade Singly early in case of haploid and along with another factor of similar or type in case of dIploid

Allele- There are various form of gene which are found at same place or locals on homolog is chromosomes and controlled the same character.

Genotype - it is the presentation of genetic constitution complement of an individual with respect to one or more character.

Phenotype- It is Ops available external manifestation of morphological of you logical charactersame as dominant homozygous or heterozygous state.

Dominant- It is able to express its effect even in the presence of its contrasting allele it does not require company of another similar Allelefor producing its effect

Recessive- It cannot express itself effect in presence of its contrasting it can produce of simila it cannot express itself effect in places of its contrasting it can produce It’s phenotypic effect only in company of similar Allele it’s phenotypic effect only in company of similar allele.
