Question

Domestic wheat, which has 42 chromosomes, is probably hexaploid (6n), whereas the haploid number in the ancestral ones was 7. Find out the right reason as to how are such plants produced?

Options

• Due to failure of segregation of chromatids during cell division cycle.

• Due to the gain of an extra copy of the chromosome.

• Due to failure of cytokinesis after telophase stage of cell division.

• Due to the loss of an extra copy of the chromosome.

Answer 1

Due to failure of cytokinesis after telophase stage of cell division.
