Question

Name the Scientists and write how did they explain Mendel’s laws after the chromosomes were discovered.

Answer 1

The chromosome theory of heredity was put forth by Walter Sutton and Theodore Boveri. The observations that led Sutton and Boveri to develop the Chromosomal Theory of Inheritance are given below.

• In diploid cells, genes and chromosomes are found in pairs.
• During gamete production (meiosis), homologous chromosomes split apart.
• The number of chromosomes is returned to diploid status by fertilization.
• According to the chromosomal theory of inheritance, the chromosomes segregate and assort on their own.
