Usually, respiration and breathing are considered same. However, there is a great difference between respiration and breathing. Breathing: This is a constant process, that takes place constantly through out the day. This is a process of inhaling oxygen and exhaling carbon dioxide. Respiration:
Polyploidy: Polyploidy,, the condition in which a normally diploid cell or organism acquires one or more additional sets of chromosomes. In other words, the polyploid cell or organism has three or more times the haploid chromosome number. Polyploidy arises as the result of total nondisjunction of chromosomes during mitosis or meiosis. Polyploidy is common among plants and has been, in fact, a major source of speciation in the angiosperms.
Polyploidy is used in genetics and is defined as an organism or cell having more than twice the haploid number of chromosomes. Rarely is this seen in animals but it is common in plants. It is seen in some animal tissues such as muscle and red marrow. Most organisms are diploid. If an organism is polyploidy, it is due to an abnormal division of the cell. It is seen in salmon or goldfish but mostly in plants. It can occur in about 2â3 of all human pregnancies and ~15% of miscarriages. 85% never get beyond the first few cell divisions. Most wheat types are polyploidy.
