CELL DIVISION

THE CELL CYCLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Based on current knowledge about the reproductive differences in species how would you expect the genetic variation to compare between a population bacteria and a fruit fly population?
A
The fruit flies have more genetic variation because they inherit genetic information from both parents.
B
The fruit flies have less genetic variation because they reproduce sexually.
C
The bacteria have less genetic variation because the cells of a bacteria are smaller.
D
The bacteria have more genetic variation because reproduction happens asexullay.
Explanation: 

Detailed explanation-1: -Penguins, for example, have twice as much genetic diversity as humans. Fruit flies have 10 times as much. Even our closest living relative, the chimpanzee, has been around at least several million years.

Detailed explanation-2: -Some common mutations seen in fruit flies include wing structure and eye color variations. Mutant wings may be short or backward. Fruit flies are known for their red eyes, although mutations cause certain specimens to have golden or white eyes. Mutations also sometimes result in eyeless flies.

Detailed explanation-3: -And then on a practical level, Drosophila has a short life cycle of about two weeks, and females have a lot of offspring-they can lay hundreds of eggs in a few days. Both these features make them a great system for genetic experiments.

Detailed explanation-4: -Genetic variations that alter gene activity or protein function can introduce different traits in an organism. If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection).
