Actually they are right. STR analysis with 13 markers gives a 1 in 10 billion or greater chance that two people will have the same pattern. So we can conclude that he was in the crime scene.<span> STR analysis with 13 markers should be sufficient to distinguish between any two people on the planet.</span>
the answer is : Marco carry the gene for color blindness, but Lauren did not.
Color blindness is a usually a genetic (hereditary) condition (you are born with it). Red/green and blue color blindness is usually passed down from your parents. The gene which is responsible for the condition is carried on the X chromosome and this is the reason why many more men are affected than women.as man has a 2 chromosomes X and Y,
so both the chromosome can be transfered into the baby as the coming gene normally carry the men's heridity. The effects of color vision deficiency can be mild, moderate or severe depending upon the defect. If you have inherited color blindness your condition will stay the same throughout your life – it won’t get any better or worse.
People with normal color vision have all three types of cone/pathway working correctly but color blindness occurs
when one or more of the cone types are faulty. For example, if the red cone is faulty you won’t be able to see colors containing red clearly. Most people with color blindness can’t distinguish certain shades of red and green. That's why this comes into the gene once in the generation.

1. The reason why the dark-colored variety was in greater numbers present in the polluted environment is that the dark-colored moths were better adapted to the environment.
The pollution killed the lichens which caused the tree trunks to have a much darker color than before. The dark color of the tree trunks permitted the dark-colored moths to hide and camouflage from the predators. That is why the dark-colored moths were better adapted to the polluted environment.
2. There could be many reasons why the light-colored variety was not completely eliminated from the polluted environment. The light-colored variety could be less effectively adapted to the polluted environment, but it wasn't completely extinct.
This is because the light-colored moths could be resting and hiding in other places and not on the tree trunk. Also, some of the light-colored moths found in the polluted environment could have migrated from other less polluted places. Finally, some of the dark-colored moths could be carrying the allele for the light color.
3. The air pollution control laws could help reverse the environmental destruction caused by the industrialization. This could help in significantly decreasing the air pollution and restoring the balance of the ecosystem. If the pollution decreases, the population of lichens could recover and the tree trunks could be covered again with lichens. This, in turn, would make the color of the tree trunks lighter and the light-colored moths could hide and camouflage on the tree trunks again.
4. The diagram shows the percentage of each moth variety in the two different environments, the polluted and the non-polluted environment.
The percentage of dark-colored moths in the non-polluted environment was closest to 15% and in the polluted environment, it nearly rose to 70%.
The percentage of the light-colored moths in the non-polluted environment was nearly 85% and in the polluted environment it was closest to 24%.
5. The correct answer is "a given trait can be a favorable adaptation in one environment, but not in another environment".
An evolutionary adaptation is a term referring to the characteristics of an organism which help him survive in a specific environment. If the environmental conditions change, the characteristics which were once favorable may no longer be.
This is what all the above information shows; any change in the environment can make a once favorable adaptation disadvantageous.
