Although selection operates against deleterious alleles in populations, they are rarely lost from these populations. For example

, most deleterious recessive alleles in population have equilibrium q values slightly above 0. Why might that be?

Answer:

Deleterious alleles appear sporadically in a population

Explanation:

A population with a deleterious allele will have no or few individuals that have the ability to pass along these traits. These alleles appear less in a population because of selective pressure but they are not always absent. The alleles appear less often but are are not always passed on and the others that are genetically fit are able to pass along their genes. The reason the population equilibrium is not zero is because these alleles do appear but they are not necessarily passed along. These individuals may not be able to reproduce or reach the age of reproduction.

Deleterious alleles appear more often, making individuals less fit genetically, i.e. they pass fewer copies of their genes to future generations. Put another way, natural selection purges the deleterious alleles.

PSYCHO15rus [73]

Answer:

the flu cannot be "Cured" but can oly be surpressed so it in inactive. only the body white blood cells can kill and fully remove the virus.

this is questiponed because it is true that it is limited to only one person, but this person may not of even had the flue to begin with. the the second question is which flue did the person have. swine flu is deadly and cannot be removed with antibodies or antibiotics. which is a pain because this flue kills the body.

the second things that is questioned is, is the antibiotic stable enough for everyone?

everyone has a different immune structured in different ways. some antibiotics will not help certain people because of the lack of lipids and enzymes in the hosts blood. this can be fatal because the body has a natural buffer in the blood that the antibiotic can easily damage and kill the host.

Explanation:

Every human body will react differently.

Natalija [7]

Answer:

The greenhouse effect increases temperature, putting the natural instinct to hibernate on hold. Mating seasons rely on warming and cooling trends, as well. Even a slight increase in temperature causes animals to mate earlier.

Dimples (D) and brown hair (A) are dominant traits. Answer the following questions based on the dihybrid cross shown:
ira [324]
1. DDAA, DdAa
2. DDaa, Dada
3. ddAA, ddAa
4. ddaa
5. The phenotypic ratio is 9:3:3:1 where 9 combinations will produce offspring with both dominant phenotypes (dimples and brown hair), 3 will produce offspring with one dominant phenotype and one receive phenotype (dimples, blonde hair), 3 will produce offspring with one receive phenotype and one dominant phenotype (no dimples, brown hair), and one will produce offspring with both recessive phenotypes (no dimples, blonde hair)
