Question

Cause of chromosome laggards in meiosis is?

• A. Inversion
• B. Dicentric chromosome
• C. Acentric chromosome
• D. Duplication of a gene

Answer 1

The correct option is B Dicentric chromosome

A laggard is defined as a chromosome that does not overlap along the long axis of the spindle with any of the properly segregating chromosomes. A dicentric chromosome is an abnormal chromosome with two centromeres. It is formed through the fusion of two chromosome segments, each with a centromere, resulting in the loss of acentric fragments (lacking a centromere) and the formation of dicentric fragments.

So, the correct answer is 'Dicentric chromosome'.
