Which observation would be the best evidence for a recent founder event or population bottleneck?

Biology

Bingel [31]3 years ago
7 0
The best evidence of such phenomena could be a population's genetic variation decrease.
When a population bottleneck occur it means that for some reason (i.e. environmental events) the size of a population is largely reduced. This leads to reduction of the genetic variation in that new smaller population. When a bottleneck occur, the founder effect is normally seen, which is that one population is established by a small group of a previously larger population leading once again the genetic variation, now though with a bigger population, to be very reduced.

What are some of the problems with forensic evidence and its use in the
VladimirAG [237]

Answer:

- Not enough evidence

 Sometimes there isn't enough evidence in a case to state fully what happened which can result into false accusation. It can also make the jury become confused and struggle to find whos the right murder due to the lack of evidence.  

- misinterpreted evidence

If a forensic scientist looks at a piece of evidence with the wrong theory they might try to prove their theory by trying to get proof out of it which can cuse a domino effect to where the wrong person can be accused of the wrong thing.

- false evidence

The evidence may be planted and the forensic science can look at it the wrong way similar to misinterpreted evidence. usually forensic scientist can see that it has been planted but when they figure that it has then its even harder to look for the real evidence. and it would take a longer process. And if they present the false evidence in court it may take a bad turn.

Schach [20]

Answer:

This is one example of a chimp DNA diagram

A G C T A C A G A G

A is Adenin

G is Guanine

C is Citosin

T is Thymine

Explanation:

Adenine

Adenine is an organic molecule found in DNA, ribonucleic acid (known as RNA) and adenosine triphosphate, better known as ATP.

Guanine

Guanine is a purine base found in DNA and RNA that binds exclusively with cytosine to form ribonucleosides called guanosine or deoxyribose to form deoxyguanosine.

Thymine

Thymine is a pyrimidine base found in DNA that binds to adenine.

Cytosine

Cytosine is a pyramid-shaped nitrogenous base that binds to guanine in RNA and DNA as nucleotides and functions as part of the genetic code.
