Answer:
Natural selection is least likely to occur in this population if:
- The resources are continuously available
For a species to survive in an area, it is essential that the place has enough resources like nutrients, space, water etc. If these resources are available then there will be less chances of competition which will lead to lesser chances of natural selection.
- The number of of death rates is equal to the number of of birth rates
In an balanced ecosystem, the number of birth rates is equal to the number of death rates for a population. If the number of death rates is lesser to the number of birth rates then the competition for resources will lead to natural selection.
The answer is ‘suspect iii has 900 bp and 260 bp sized DNA fragments’
Forensic science utilizes particular sequences of DNA that are unique to people and are cut differently by restriction enzymes. These techniques are referred to as Restriction Fragment Length Polymorphism (RFLP) and the Short Tandem Repeat (STR) Analysis. In this case, there is an exact match on the crime sample and that of the suspect.
Mutations can affect the coding of "base pairs" in the chromosome of an individual by various means like:
1) by Deletion
2) by Duplication
3) by Translocation
4) by Inversion
After all that changes, codes deviates from normal information & can affect individual in negative way. In that manner, Mutations affect individual traits.
Hope this helps!
