Question

Select the incorrect statement regarding chromosomal theory of inheritance.

• A. It was proposed by Sutton and Boveri
• B. Chromosomes as the carriers of genetic material
  
• C. Chromosomes and genes occur in pairs in diploid and haploid cells
• D. The paired condition of both chromosomes as well as Mendelian factors is restored during fertilisation.

Answer 1

Answer: (C)

Chromosomes and genes occur in pairs in diploid and haploid cells

During gamete formation, both homologous chromosomes as well as genes carried by them segregate in such a way that only one of each pair is transmitted to a gamete. Hence, haploid gametes consist of only one of the chromosome or gene from the pair present before segregation.

So, the correct option is 'Chromosomes and genes occur in pairs in diploid and haploid cells'.
