Question

Given below are different statements regarding Mendel’s experiment on garden pea. Which of the statements explains why he failed to observe linkage?

• A. Genes of the traits selected by Mendel were located on four different chromosomes and behaved independently
• B. Genes selected by him were discrete and stable
• C. All the genes for seven characters were located on seven non-homologous chromosomes
• D. Pea plant does not show linkage

Answer 1

The correct option is A Genes of the traits selected by Mendel were located on four different chromosomes and behaved independently

All the genes of seven traits selected by him were located on four different chromosomes and behaved independently

Linkage is the phenomenon in which genes which are located closer to each other get inherited as a unit without assortment.

The genes of the seven characters selected by Mendel were located on four different chromosomes 1, 4, 5, 7, and the ones present on the same chromosome were also situated far apart. Hence, he didn’t observe any linkage of the genes.
