How to use in-sentence of “allele”:
– Changes in allele frequency are mainly caused by natural selection, that is, by differential survival, and contribution to the next generation.
– In a heterozygote the effect of one allele may completely ‘mask’ the other.
– There are variations between human populations, so a SNP allele that is common in one geographical or ethnic group may be much rarer in another.
– The unexpressed allele is called “recessive”.
– When all but one allele go away, one only remains.
– A person with two copies of the red-haired allele will have red hair, but it will be either auburn or bright reddish orange depending on whether the first gene pair gives brown or blond hair, respectively.
Example sentences of “allele”:
– Often, one allele will be “dominant”, meaning that the living thing looks and acts as if it had only that one allele.
– Because the heterozygote survives, so does the HgbS allele survive at a rate much higher than the mutation rate.
– In this case the functional product formed is a little different or is intermediate between the product produced by to the dominant allele and the recessive allele.
– A fixed allele is one allele that exists for a particular population.
– They think this allele helps protect against episodes where the brain does not get enough oxygen.
– That allele is said to be fixed.
– One phenotype has a dominant brown allele and a recessive blond allele.
– Thus, equations can be written in terms of allele frequencies, and hypotheses about how phenotypes are inherited can be tested from population data.
– If the frequency of any allele is above 1% it is probable that natural selection is maintaining it at this level.
– The allele that masks the other is said to be dominant to the latter, and the alternative allele is said to be recessive to the former.
– During microevolution changes in allele frequencies definitely do occur.
– A fixed allele is homozygous for all members of the population.
- Often, one allele will be "dominant", meaning that the living thing looks and acts as if it had only that one allele.
- Because the heterozygote survives, so does the HgbS allele survive at a rate much higher than the mutation rate.
