Why do fruit flies have 8 chromosomes?
Explanation: Somatic cells are diploid , which means they have two sets of chromosomes, one set from the mother and one set from the father. The somatic cells of fruit flies contain eight chromosomes, which means they have two sets of four chromosomes. Meiosis is the process by which sex cells are produced.

Why do Geneticists study fruit flies?
Fruit flies have a very simple genetic structure , which makes them ideal for genetic research. It is useful to study mutant fruit flies, as their quick reproduction rate allows scientists to observe the advantages and disadvantages of certain mutations.
How many chromosomes do bananas?
This is the first completed sequence of the 11 chromosomes of banana and it provides the first detailed genetic blueprint of the most important fruit crop in the world and one of the most important food crops after staple cereals and cassava.
