This is on account of every chromosome just has up to 50 units so when it surpassed this number it's on an alternate chromosome, along these lines it can't be connected.
One can decide whether qualities are connected or not by taking a gander at the posterity and deciding the recombination recurrence you can do this by taking the aggregate number of posterity that were recombined and partitioning it by the aggregate
Plants need oxygen to survive , no oxygen mean the plant will diePlants do need oxygen to survive. They respire (take in oxygen, give off carbon dioxide) the same way that animals do. The difference is that during the day, plants also perform photosynthesis, in which they take in carbon dioxide and give off oxygen.Plants require oxygen for respiration to carry out their functions of water and nutrient uptake. In soil adequate oxygen is usually available, but plant roots growing in water will quickly exhaust the supply of dissolved oxygen and can be damaged or killed unless additional air is provided. A common method of supplying oxygen is to bubble air through the solution. It is not usually necessary to provide supplementary oxygen in aeroponic or continuous flow systems.Oxygen is vital ingredient in plant survival
