What is autosomal recessive disease?
A recessive gene is one that lacks dominance and therefore, does not manifest a phenotype when the individual is heterozygous. In this case, only the dominant gene expresses a phenotype. To express a phenotype of a recessive gene the individual has to possess two copies of the gene, one from each parent.

- Dominant Phenotypes Are Not Always More Common Than Recessive Phenotypes
- Dominant Alleles Are Not Better Than Recessive Alleles
- A “Broken” Allele Can Have A Dominant Inheritance Pattern
Let’s look at a typical (i.e., rare) single-gene trait: 1. dominant allele + dominant allele = dominant phenotype 2. dominant allele + recessive allele = dominant phenotype 3. recessive allele + recessive allele = recessive phenotype Looking at this, you might conclude that the dominant phenotype is twice as common as therecessive one. But you woul...
Mode of inheritance has nothing to do with whether an allele benefits an individual or not.Take rock pocket mice, where fur color is controlled mainly by a single gene. The gene codesfor a protein that makes dark pigment. Some rock pocket mice have dark fur, and some havelight fur. The dark-fur allele is dominant, and the light-fur allele is recess...
Many genetic disorders involve “broken” genes that code for a protein that doesn’t workproperly. Since one “normal” copy of the gene can often provide enough of the protein to maskthe effects of the disease allele, these disorders often have a recessive inheritancepattern. But not all diseases alleles are recessive. Keratin proteins link together t...
Recessiveness, in genetics, the failure of one of a pair of genes (alleles) present in an individual to express itself in an observable manner because of the greater influence, or dominance, of its opposite-acting partner.

recessive. Refers to a trait that is expressed only when genotype is homozygous; a trait that tends to be masked by other inherited traits, yet persists in a population among heterozygous...
