Answer in Brief
Short Answer Question.
Explain the chromosomal theory of inheritance.
The chromosomal theory of inheritance was proposed by Sutton and Boveri.
Following are the postulates of chromosomal theory of inheritance:
- Chromosomes are found in pairs in somatic or diploid cells.
- During gamete formation, homologous chromosomes pair, segregate and assort independently at meiosis. Due to this, each gamete contains only one chromosome of a pair.
- Hereditary characters are carried by chromosomes which are present in the nucleus of these gametes.
- Gametes (sperm and egg) contain all the hereditary characters. They form the link between parents and offsprings.
- The union of sperm and egg during fertilization restores the diploid number of chromosomes.
