Chromosomal Theory of Inheritance
BIOXII05: PRINCIPLES OF INHERITANCE AND VARIATION

342116 Which of the following statement for chromosomal theory of inheritance is incorrect?

1 Pairing and separation of a pair of
chromosomes would not lead to the
segregation of a factor they carried
2 Behaviour of chromosomes is parallel to
the behaviour of genes
3 The two alleles of a gene pair are located
on homologous sites on homologous
chromosomes
4 Chromosomes as well as genes occur in
pairs
BIOXII05: PRINCIPLES OF INHERITANCE AND VARIATION

342117 One pair segregates independently of other pair is always applicable for

1 Chromosome
2 Gene
3 Neither chromosome nor gene
4 Both chromosome and gene

342118 Mendel’s work remained unrecognised till 1900 because
(a) Mendel’s approach of using mathematics to explain biological phenomena was totally new and unacceptable to many of the biologists of his time
(b) Concept of genes (or factors, in Mendel’s words) as stable and discrete units that controlled the expression of traits and, of the pair of alleles which did not ‘blend’ with each other, was not accepted by his contemporaries

1 (a) is correct only
2 (a), (b) correct
3 (b) is correct only
4 Both are wrong
