Question

Out of three characters on chromosome no. 4, two characters indicate linkage and not mentioned by Mendel. These characters were

• A. Pod form - stem length
• B. Pod form - pod position
• C. Pod form - pod colour
• D. Pod position - stem length

Answer 1

The correct option is A Pod form - stem length

The chromosome no. 4 of pea plant carries genes for flower position, pod form and plant height. Out of these three genes, the two genes namely the gene for pod form and the one for plant height are closely placed on the chromosome that they show linkage. However, the gene for flower position is located far apart from the other two genes and do not show linkage. Hence, option A is correct.
