Respuesta :
a recessive allele, not expressing its gene so to speak, when in heterozygotes its overcome by a dominant allele. but in homo it is only combined with the same recessive allele.
The recessive allele is an allele that is not expressed in heterozygotes but is expressed in homozygotes.
What is allele?
Each of two or more alternative forms of a gene that arise as a result of mutation and are found on the same chromosome is referred to as allele.
The effect of one allele in a heterozygous genotype completely masks the effect of the other in case of complete dominance. The masking allele is dominant over the other allele, while the masked allele is recessive.
Thus, a recessive allele is an allele that is not expressed in heterozygotes but is expressed in homozygotes.
