Discuss the contribution of Sutton and Boveri by. Making a comparison between the behaviour of chromosomes and genes during meiosis, to explain Mendel's Laws.

Text Solution

Verified by Experts

Walter Sutton and Theodore Boven noted, that the behaviour of chromosomes was parallel to the behaviour of genes and used chromosome movement to explain Mendel.s laws. Chromosomes as well as genes occur in pairs. The two alleles of a gene pair are located on homologous sites on homologous chromosomes.
Comparison between the behaviour of chromosomes and genes
Chromosomes
Occur in pairs
Segregate at the time of gamete formation such that only one of each pair is transmitted to a gamete.
Independent pairs segregate independently of each othar.
Genes
Occur in pairs
Segregate at gamete formation such that only one or each pair is transmitted ta a gamete.
One pair segregates independently of another pair.
Sutton and Boveri argued that the pairing and separation of a pair of chromosomes would lead to the segregation of a pair of factors they carried. Sutton united the knowledge of chromosomal segregation with mendelian principles and celled it the chromosomal theory of inheritance.
