Dictionary » R » Recessive RecessiveDefinition adjective (general) Going back; receding. (genetics) Of, or pertaining to, a gene (or allele) whose phenotypic expression is masked by a dominant gene (or allele). noun (1) A recessive allele or trait. (2) An organism whose recessive trait is discernible or expressed.
In genetics, a recessive gene or allele is one in which the effect is not tangible, or is masked by the effects of the dominant gene. The recessive trait may be expressed when the recessive genes are in homozygous condition or when the dominant gene is not present. That happens when an organism inherits a pair of recessive genes from its parents.
Related forms: recessiveness (noun), recessively (adverb).
Compare: dominant. ![]()

Results from our forummutation-selection balance... is equal to μ, the mutation rate (p = μ). We can use the same principles to predict the relationship between mutation and selection against recessive alleles. The Hardy-Weinberg principle showed that most copies of harmful recessive alleles are found in heterozygotes and are thus protected ...

Pedigree AnalysisI want to know if I have this correct because I am confused. I think this is x-linked recessive is that right :?: since it can fall into this category 1.Usually more males than females are affected. 2. Affected sons are usually born to unaffected mothers; thus, the ...

Re: Genetics problems1. a. Given a plant was heterozygous for pod shape and homozygous recessive for plant size b. do you know Punnett square? c. the same as above d. the same as above and above above, just combined 2. Pure breeding means they are homozygous (thus all progeny ...

Genetics problems... a one gene – two allele system with tall size being completely dominant to dwarf size. Given a plant was heterozygous for pod shape and homozygous recessive for plant size: a. What is the phenotype of this plant? b. If this plant was crossed to a dihybrid (heterozygote), what would be the phenotypic ...

Re: Muscular dystrophy inheritance question... sure thing). The male shows the sequence ATGGGAAG, matching the female allele that does not contain the possible splice site. This appears to be a recessive allele. I am still puzzled by the top trace. Is it possible that this is representing the sequence of cDNA across a splice site that is spliced ...
