Перевод: phenotype
[существительное] фенотип
Тезаурус:
- The instrument with which we shall purge our minds is the idea that I call the extended phenotype.
- Mutations in several Pax genes lead to severe developmental abnormalities: (1) a mutation in the paired box of murine Pax-1 leads to the undulated phenotype which exhibits distortions of the vertebral column; (2) a mutation in the Pax-6 gene leads to the semidominant Small eye phenotype in mouse and a mutation in the putative human homologue of this gene may be responsible for the aniridia disorder; (3) mutations in the putative human homologue to Pax-3 ( HuP2 ) occasionally lead to hearing loss associated with Waardenburg's syndrome, whereas in mouse a deletion in Pax-3 causes the splotch phenotype which is associated with spina bifida, exencephaly, a tail flexion defect and deficiencies in neural crest cell derivatives.
- Dozens of gene families have been described with precise effects on the phenotype of organisms.
- This leads to what I have called the Central Theorem of the Extended Phenotype: An animal's behaviour tends to maximise the survival of the genes "for" that behaviour, whether or not those genes happen to be in the body of the particular animal performing it .
- But the doctrine of the extended phenotype has taught us that it needn't have been so.
- In the world of the extended phenotype, ask not how an animal's behaviour benefits its genes; ask instead whose genes it is benefiting.
- The Extended Phenotype is a long book and its argument cannot easily be crammed into one chapter.
- But the change in phenotype would be gradual and concurrent in all individuals; the genetic variation and differences in fitness between individuals in the population would be kept to a minimum.
- Let me end with a brief manifesto, a summary of the entire selfish gene/extended phenotype view of life.
- In The Extended Phenotype I attempt to work out an answer to this difficult problem.
- The unit of selection is the individual phenotype: this, however, implies that the ultimate unit of selection is the gene that contributes successful traits.
- If the change in phenotype is deleterious and selection acts against it, then many individuals would suffer the same fate.
- The distinction between genotype and phenotype reflects a division of labour between nucleic acids and proteins.
