<p>why is genetic polymorphism important to evolution?
1.individual variability provides the raw material for natural selection to act on
2.genes cant mutate unless they are polymorphic
3.only heterozygous individuals are selected in natural populations
4. the hardy weinberg equilibrium is less likely to be disturbed in polymorphic population
5. none of the above; genetic polymorphism is not important to evolution</p>
<p>in a population of wildflowers, the frequency of the alle for the red flowers was 0.8 what was the frequency of the white allele the only other allele for flower color?</p>
<p>it is .2?</p>
<p>refer to the question above what is the frequency of homozygous white flower plants in the population?
1. .04
2. .16
3. .32
4. .48
5. .64</p>
<p>refer to the question above what is the frequency of the plants in the population that are heterozygous for flower color?
1. .04
2. .16
3. .32
4. .48
5. .64</p>
<p>a virus killed most of the seals in the north sea eg. dropped the population from 8000 to 800. in an effort to help preserve the species scientists caught 20 seals and used them to start a new population in the northwest pacific ocean. what of the following factors would most likely have the least impact in this new population?
1. founder principle
2. random mating
3.genetic drift
4.bottleneck effect</p>
<p>does inbreeding occur in plants?</p>
<p>an individual of which of the following species is likely to have the highest level of heterozygous genes?
1. fish
2.land snail
3. self pollinating plant
4. bird
5. mammal</p>
<p>yes, it's .2
homozygous recessive population = q^2 = .04</p>
<p>p^2 +2pq + q^2 = 1
homo dominant + hetero + homo recessive = 1
2 x .8 x .2 = .32</p>
<p>I haven't taken bio since 10th grade (senior now) so I can't really help with the other two, and I'm not sure if these answers are right either. I'm just procrastinating, actually.</p>

<p>Answer: 1. genetic polymorphism maintains a variety of alleles in the gene pool, allowing for nat selection to take place</p>

<ol>
<li>I don't think random mating would have NO effect, but the effect of the others in such a small population would be much greater. </li>

1. fish
2.land snail
3. self pollinating plant

<p>my guess is 3. the others seem too random. lol sorry I'm not sure about this one.</p>
<ol>
<li>individual variability provides the raw material for natural selection to act on</li>
</ol>
<p>Yes it is .2</p>
<p>.04</p>
<p>.32</p>
<p>Random mating. (Founder effect and bottleneck effect are 2 variations of genetic drift, which affects small populations such as the seal pop. Random mating would have no effect and actually contributes to lesser change in gene pool as observed in the hardy weinberg theorem)</p>
<p>The last question is quite ambiguous, but I would say it can't be 3, because there is no genetic variability and thus less heterogygous genes. Perhaps the original question was "least level of heterozygous genes?" If not, I would go with mammals.</p>
