Question

Which of the following represents a natural mechanism by which haploids may arise during development?

Options

• Chromosome doubling

• Hybridization between two species

• Chromosome elimination or loss during development

• Endoreduplication

Answer 1

Chromosome elimination or loss during development is listed as one of the natural ways haploids may arise. This process involves the progressive loss of chromosomes from a cell lineage, eventually resulting in a cell with only a single set of chromosomes.
