If a trait is recessive, this means it will take gene(s) for the trait to manifest itself in one's offspring.

Homozygous recessive

Explanation:

Gregor Mendel discovered that a gene comes in two different forms called ALLELES. Each allele is responsible for the different traits of that same gene. Mendel later discovered that one allele called DOMINANT allele is capable of masking the expression of another allele called RECESSIVE allele, in a gene. Hence, in a heterozygous state I.e combination of both alleles, the dominant trait will be expressed.

N.B: HOMOZYGOUS means contains identical or same alleles for a gene while HETEROZYGOUS means contains contains different alleles (dominant and recessive) for a gene.

Based on this analogy above, a dominant trait encoded by a dominant allele will be expressed in an individual when the gene is either HOMOZYGOUS or HETEROZYGOUS for both alleles while a recessive trait will only be expressed when the gene is HOMOZYGOUS for the recessive alleles.
