The Chromosome Theory of Inheritance
What are non-allelic genes?
Who had proposed the chromosomal theory of the inheritance?
In his classic experiments on pea plants, Mendel did not use?
Who discovered the gene?
- Pod shape
- Pod colour
- Location of flower
- Location of pods
Sutton and Boveri explained Mendel’s laws using ___.
Movement of chromosomes during cell division
Movement of nuclei during cell division
Movement of cell organelles during cell division
Movement of proteins during cell division
Which one from those given below is the period for Mendels hybridization experiments?
- Seven years (1865−1872)
- Seven years (1856−1863)
- Seven years (1853−1860)
- Fourteen years (1853−1867)
I. The chromosomal movement during meiosis had been worked out by 1902.
II. Mendel suggested that factors are discrete units and was able to provide physical proof for its existence.
III. Advancements in microscopy helped scientists to carefully observe cell division and discover chromosomes.
- Statements (I) and (II) are correct, but statement (III) is incorrect
- Statements (I) and (II) are incorrect, but statement (III) is correct
- Statements (I) and (III) are correct, but statement (II) is incorrect
- All statements are correct
explain the mechanism of hereditary changes
- There is a considerable amount of variation seen in pea plant hybridisation results
- Factors are inherited as discrete units and do not show blending
- Genes are found on chromosomes
- Behaviour of chromosomes is parallel to behaviour of genes
How do you know if two genes are linked together?
A nucleotide is composed of
Nitrogenous base + sugar + phosphate
Nitrogenous base + sugar
Nitrogenous base + phosphate
None of these
