Sex Ratio

Genic balance theory of sex determination in Drosophila has been proposed by Bridges. Sex is determined by the ratio of the X-chromosomes and the set of autosomes.

The theory where ratio between the number of X_ chromosomes and number of complete sets of autosomes will determine the sex is known as

If X/A Ratio of two Drosophila is 0.6 and 0.33 respecively what would be their sex :-

Sex determination ratio in an organism is given by (X)/(A) = 1.5 , then the organism will be
