Does corn go through mitosis or meiosis?

For example, corn tassel (produce male gametes – pollen) and ear (producing the female gametes – eggs). Unlike clonal varieties which involve only mitosis, seed production for seed cultivars requires meiosis.

Does polyploidy occur in humans?

Polyploid cells are found in diverse taxa (Fox and Duronio, 2013; Edgar et al., 2014), and in fact entire organisms can be polyploid, or polyploid cells can exist in otherwise diploid organisms (endopolyploidy). In humans, polyploid cells are found in critical tissues, such as liver and placenta.

What is origin of maize?

THERE have been three general theories regarding the origin of maize: (1) that it originated from pod-corn, Zea mays tunicata, which differs from normal maize primarily by a single dominant gene governing the development of a brittle, disarticulating rachis and the production of prominent glumes enclosing the seeds; (2 …

What is Dihaploid?

Dihaploid refers to a haploid cell in which its nucleus contains two copies of the set of chromosomes. For instance, haploids of tetraploid species are called dihaploid. A dihaploid occurs as a result of the spontaneous or induced chromosome doubling in haploid cells during embryogenesis.
