Answer:

There are no options in this question but generally a sample of DNA can be increased;

By using Polymerase Chain Reaction (PCR) technique.

Explanation:

This question describes the application of making molecular biology to solving a crime problem; a branch called forensics. In this case where an insufficient small amount of DNA sample was recovered from the blood in a crime scene, the polymerase chain reaction technique, commonly known as PCR can be used to increase the DNA sample.

In the 1980's, a molecular technique used to amplify part of a template DNA strand to produce several copies of it, was invented by Kary Mullis and his colleagues. This amplification refers to the numerical increase in the number of DNA sequence.

Before a captive breeding program and subsequent reintroduction of the black-footed ferret it is believed that their total popul
irga5000 [103]

Answer:

a) 99.93%

b) 99.98%

Explanation:

Given that:

Total population size was only around 18 individuals ( for  black-footed ferret)

If the annual survival rate in the wild was 0.4%.

a)

What is the probability that all 18 would have died in a single year?

To find that; we multiply the annual survival rate in the wild with the total population; which is:

(0.4%×18) = 0.072%

Then; we subtract it from a total of 100% in order to determine the probability that all 18 would have died in a single year.

= (100.00% - 0.072%)

= 99.93%

b)

What is the probability that all 18 would have died in a single year if canine distemper was present?

Given that;

Because of the presence of canine distemper disease, the annual mortality rate might have been as high as 0.89.

To determine the probability; we have:

1 - Annual mortality rate = annual survival rate

1 - 0.89 = 0.11 %

Therefore, 0.11% of 18 individuals = (0.0011 × 18)

= 0.0198%

Probability that all 18 would have died in a single year if canine distemper was present = 100 - probability of annual survival rate

= (100 - 0.0198)%

= 99.98%
