Some alleles are neither dominant or recessive and many traits are controlled by what?

Each person has two alleles of one particular gene, which controls one particular characteristic, such as a person's blood group. An allele may be either dominant, recessive, or codominant. A dominant allele would dominate the other allele in the chromosomes, meaning only the dominant allele would contribute to an organism's characteristics. An example of this is the A blood group, which is dominant to the O allele. However, if an individual has both A and B alleles, A and B are codominant, as they both exhibit effects on an organism's characteristics (the blood group). This results in an AB blood group - a combination of the effects of two genes!


Can antibiotics exhibit side effects four days after completing the course?

Unfortunately antibiotics can and do exhibit side effects four days after completing the course. I never start antibiotics without taking acidophilus and eating lots of yogurt.


Does the story his grandfather's old ram exhibit certain effects of a bad memory?

yes


Does matter dual nature?

Yes. Sub-atomic particles exhibit both particle effects (no surprise) but also wave effects. This has been known since about 1927.


Why are boys more dominant in baldness than females?

The term dominant is a misnomer here as the trait is not dominant or the number of women with the trait would be much higher. Pattern baldness is a sex-linked trait. Male pattern baldness alleles are present on the X chromosome which means that only one copy of the allele is required for a male to exhibit the trait (the y chromosome, being much smaller, doesn't have the gene locus for this trait). Females must have 2 alleles for the characteristic in order to exhibit the the trait.


How many alleles can occur at a microsatellite locus?

Most alleles are either present or absent, which gives two choices. Those which are not, say for skin color of mixed-race heritage, can exhibit a large number of possibilities, and though the exact count might be difficult to determine, it is of course finite.


Blood type A marries blood type B their offspring exhibit?

It is possible for their offspring to exhibit type AB, A, B, or O, depending upon the parental genotype, which is unknown. The blood type exhibited, also referred to as phenotype, is due to the dominant A and B alleles. Every person inherits two alleles for each gene, one from each parent. The type A may have inherited two A alleles or an A allele and an O allele, the O being masked by the dominant A because it is a recessive trait. Therefore they exhibit the phenotype A, but could potentially pass on an O allele to any offspring. The same goes for the type B parent (could be BB or BO). The exact genotype (AA/BB or AO/BO) is not determined through simple blood testing, so the exact phenotype of the offspring can not be predicted.

The both exhibit doppler effects.


Are there any medicines that enhance the production of growth hormone in human body without any side effects?

All growth enhancers exhibit negative side effects, many of which will not appear for years. Some can be debilitating.


Do animals exhibit phenotypic plasticity?

plasticity is specific to plants because they cannot move in response to stimuli, or to escape or adapt to a certain environment. if an animal doesn't like the current environment they're in, they'll simply move out of it, but with plants with root systems, it's much more difficult if not impossible, therefore plasticity.


Some antibiotics cause patients to exhibit digestive side effects These side effects are most often the result of what?

bacteria being killed in the digestive tract, because the lack of intestinal bacteria causes the person to not feel well.


Is exhibit pronoun or common noun?

Exhibit can be a noun or a verb: The art exhibit made him exhibit sympathetic feelings. It is not, however, a pronoun.
