Disccus the genic balance mechanism of sex determination in Drosophila ?

Explanation

Drosophila has eight chromosomes 3 pairs of autosomes and one pair of sex chromosomes. Eventhough Drosohila possesses XX and XY sex chromosomes , the Y c hromosome does not have any role in determination the sex of the individuals. the sex in Drosophila is determination by the ratio of number of X chromosomers to that of teh number of sets determination is achieved by a balance of male determinants of the X chromosome (X ). and male determination the autosomes
(A ) . this type of sex determination is called Genic Balance system.
(i) if `(X )/(A )` ratio i.e., two X chromosomes and two sets so autosomes `-(2)/(2) = 1.00` the individual will be female.
(ii) if `(X )/(A ) ` ratio i.e., oen X chromsomes and two set of autosomes `-(1)/(2) -= 0.5` the individual will be male.
(iii) if `(X )/(A)` ratio is between 1.00 and 0.5 the individual will be inter sex .
(iv) if `(X)/(A)` ratio is above 1.00 the individual will be meta female.
(v ) if `(X )/(A)` ratio is below 0.50 the individual will be meta male .
