XO in drosophila result in sterile:
Correct answer: B. Male
- A. Female
- B. Male
- C. Both (A) & (B)
- D. No effect
Explanation
XO in drosophila results in a sterile male. As XO means the absence of the second chromosome. The male has only one X chromosome and one Y chromosome, while the female has two X chromosomes. So, when offspring of drosophila carry one X chromosome from a male and one X chromosome from a female it results in a normal female but when offspring of drosophila carry one X chromosome from a female and no chromosome from a male then it results in a sterile male.

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
