Definition of recessive in English: recessiveadjective rɪˈsɛsɪvrəˈsɛsɪv 1Genetics Relating to or denoting heritable characteristics controlled by genes which are expressed in offspring only when inherited from both parents. 〔遗传〕隐性的。常与DOMINANT 相对 Often contrasted with dominant Example sentencesExamples - I suspect we shall see the resurgence of all sorts of recessive traits.
- It would operate like inbreeding, which increases the odds of offspring inheriting the same deleterious recessive allele from both parents.
- Short hair being dominant over long, breedings between shorthair and longhair cats will produce only shorthair kittens, unless the shorthair parent is carrying the recessive gene for long hair.
- Self-pollination in these strains was found to be controlled by duplicate, recessive genes.
- On occasion, families are observed where both parents have a recessive single gene disorder and yet have normal offspring.
- Secondly; reductions in the available gene pool have almost always resulted in further proliferation of genetic disorders as recessive genes have a higher probability of combining.
- In so-called recessive disorders, such as sickle cell disease, your child needs to inherit two bad copies of the gene - one from each parent - to develop the disease.
- Normally, people do not have one blue eye and one brown eye, or half brown hair and half blond hair because most genetic traits are the result of the expression of either the dominant or the recessive genes or alleles.
2Undergoing an economic recession. 经济萧条的 the recessive housing market 萧条的住宅市场。 Example sentencesExamples - The real growth was 1.6% in a recessive global economic climate.
- In a transition period, however, this may lead to a recessive pressure on the economy.
- There are a number of ways in which financial planning can pay off, even in a recessive economy.
- The recessive 1930s brought the reversal of this globalism while a new one was later formed during the Cold War.
- Despite the recessive market we face, we are optimistic that more business will be done than last year.
- In order to stimulate a recessive economy and pay for the cost of escalating welfare programs, Congress will add to the national debt.
3Phonetics (of the stress on a word or phrase) tending to fall on the first syllable. 〔语音〕(词或短语重音)逆行的,易移至词首音节的 recessive stress is characteristic of British English Example sentencesExamples - In modern English all the disyllabic and trisyllabic words have only recessive stress, e.g. colour, marriage.
4Linguistics Tending to fall into disuse. 〔语言学〕易废弃不用的 this variant was a low-status and recessive feature Example sentencesExamples - They have the largest number of recessive features of all West African languages.
- The older system is understood to be recessive.
noun rɪˈsɛsɪvrəˈsɛsɪv Genetics A recessive trait or gene. 〔遗传〕隐性性状;隐性基因 Example sentencesExamples - Instead selection causes the same increase in allele frequency in both dominants and recessives, at least early on when the fates of nearly all alleles are determined.
- If two of these recessives meet in an individual, their version of the trait will be expressed.
- Almost all mutants were found to behave as simple Mendelian recessives.
- But regardless of why most incompatibilities act as recessives, the present results leave little doubt that they do.
- Thus deleterious recessives had not been eliminated from the population to the extent that consanguineous matings were harmless in terms of offspring viability.
Derivativesadverb Female carriers of X-linked recessively inherited disorders can often be identified by some outward expression of the disorder. Example sentencesExamples - The most common one in the United Kingdom is Friedreich's ataxia, which is inherited recessively, often coming into a family out of the blue when two carrier parents have a child who develops ataxia symptoms.
- A line of briard dogs has been identified that is affected by an autosomal recessively inherited retinal disease resulting in severe, early onset visual impairment.
- It can be inherited either recessively or dominantly.
- This recessively inherited disorder classically presents during infancy and early childhood with a severe illness characterised by encephalopathy and hypoglycaemia.
noun Consequently recessiveness of the two mutations is well established. Example sentencesExamples - I don't think that anything is known yet about the number, position, dominance, co-dominance or recessiveness of genes for behavior.
- To test for recessiveness or dominance of the mutations, each mutant was crossed with a strain of the opposite mating type, either Y090 or Y091.
- Mendel's peas were used to demonstrate this recessiveness - in two generations I have to admit.
- The concept of dominance and recessiveness is not particularly relevant in X-linked inheritance.
noun In any case, these low estimates are in at least qualitative agreement with other evidence suggesting the recessivity of beneficial mutations. Example sentencesExamples - Their work showed that ‘…the recessivity of mutants is an inevitable consequence of kinetic properties of enzyme-catalyzed pathways and that no other explanation is required’.
- There has been no investigation of the mechanism of recessivity of the two most recessive classes.
- They suggest that ‘In fact, if mutant recessivity were not general, it would throw considerable doubt on the whole of enzymology and the study of intermediary metabolism.’
- Moreover, Y-linked mutations do not encounter the problem of recessivity or sexual antagonism, and thus any advantageous mutation has a much better chance of becoming fixed in the population than the autosomal or X-linked ones have.
