Question

Who proposed chromosomal theory of inheritance? Point out any 2 similarities in behavior of gene and chromosome?

Answer 1

Answer:

The chromosomal theory of inheritance was proposed independently by Walter Sutton and Theodore Boveri in 1902. Similarities in the behaviour of chromosomes and genes: (i) Both genes and chromosomes occur in pairs in a diploid cell (2n).

Answer 2

Chromosomal theory

Explanation:

Chromosomal theory of inheritance was proposed by Sutton and Boveri and according to this theory:

• Sutton and Boveri's chromosome theory of inheritance states that genes are found at specific locations on chromosomes and that the behavior of chromosomes during meiosis can explain Mendel’s laws of inheritance
• Chromosomes, like Mendel's genes, come in (homologous) pairs in an organism;For both genes and chromosomes, one member of the pair comes from the mother and one from the father
• The members of a homologous pair separate in meiosis, so each sperm or egg receives just one member;this process mirrors segregation of alleles into gametes in Mendel's law of segregation
• The members of different chromosome pairs are sorted into gametes independently of one another in meiosis, just like the alleles of different genes in Mendel's law of independent assortment

Similarities in the behavior of chromosomes and genes includes:

• Both genes and chromosomes occur in pairs in a diploid cell (2n)
• Both of them separate during gametogenesis to enter different gametes
