1 2 pair of autosomes and one pair of sex chromosomes
2 3 pair of autosomes and one pair of sex chromosomes
3 1 pair of autosomes and 3 pair of sex chromosomes
4 2 pair of autosomes and 2 pair of sex chromosomes
Explanation:
Drosophila melanogaster has 3 pairs of autosomes and one pair of sex chromosomes. This means it has 6 autosomes in total ( 3 pairs) and 2 sex chromosomes ( 1 pair, \(\mathrm{X}\) and \(\mathrm{Y}\) ), making it a total of 8 chromosomes in its diploid cell. This genetic arrangement determines the traits and sex of the fruit fly.

According to genic balance theory of Bridges \(\mathrm{X} / \mathrm{A}=\mathbf{1 . 5}\) will make the individual:
1 male
2 female
3 intersex
4 super female
Explanation:
According to the genic balance theory proposed by Calvin Bridges, when the ratio of \(\mathrm{X}\) chromosomes to autosomal sets \((\mathrm{X} / \mathrm{A})\) is equal to 1.5 or more, it results in the individual being, super female.

In man, the normal number of chromosomes are
1 42
2 44
3 46
4 48
Explanation:
The normal number of chromosomes in humans is 46 . This includes 22 pairs of autosomes and one pair of sex chromosomes (XX in females and \(\mathrm{XY}\) in males). These chromosomes carry the genetic information that determines an individual's traits and characteristics.

The twenty third pair of chromosomes in man is known as
1 chromatid
2 heterosome
3 autosome
4 gene
Explanation:
The twenty-third pair of chromosomes in humans is known as heterosomes or sex chromosomes. They determine an individual's biological sex, with males having one \(\mathrm{X}\) and one \(\mathrm{Y}\) chromosome (XY) and females having two \(\mathrm{X}\) chromosomes (XX). These chromosomes carry genes related to sex determination and development.
