B) The genes studied by Morgan
found on different chromosomes
C) They show many types of heredityvariations
D) They complete their life cycle in
about two weeks​

Answer 1

Answer:

a is the answer, pls mark as the brainliest

Answer 2

Option A) They are dioecious fliese.

They are dioecious fliese is not a characteristic of Drosophila melanogaster.

Drosophila:

• One of the top model species in genetics is the drosophila.
• This bacterium was used for early genetics research.
• This fly was used in tests by T. H. Morgan to support the chromosomal theory of inheritance.
• Due to its many benefits, including its two-week life cycle, low maintenance requirements, easily distinguishable phenotypic traits, four pairs of chromosomes, and ability to reproduce in vast numbers from a single mating, Drosophila has attracted a lot of study interest.
• The sexes are distinct in the population of this species, with male and female being plainly recognisable, while the Drosophila genome is 60% similar to that of humans.
• Under low power microscopes, it is clearly evident.
• The fruit fly served as a model organism for genetics studies as well as other disciplines including cancer biology, developmental biology, etc.
