Hybrid seeds are deliberately crossbred for particular traits, such as growth pattern or disease resistance. they have been hand-pollinated and are patented, often sterile, and genetically identical within food types. these plants are usually grown in a monocultural environment and are cultivated for mass production and sale. they must be sturdy to withstand mechanical picking and cross-country shipping. they do not compare to the quality and taste of heirloom plants, but they do produce large, healthy fruit that appeals to most shoppers. unlike heirloom seeds, if one saves a hybrid seed, one will not get the same plant again.
which statement can be removed and not affect the excerpt’s reliability?

Unlike heirloom seeds, if one saves a hybrid seed, one will not get the same plant again.

Explanation:

The statement that can be removed without affecting the reliability of overall paragraph is, "unlike heirloom seeds, if one saves a hybrid seed, one will not get the same plant again". This is because even if we remove this line, the paragraph still looks completely understandable, reliable and in a flow.

If we talk about hybrid plants, we know that they are produced through cross pollination of the crops with desired traits. Although they are sterile and cannot produce offspring, however the plants which are raised from these seeds are edible and quite healthy. This is why these plants have better yield and a better resistance against environmental constraints like diseases and stresses. After the production, hybrid seeds are stored and they are able to produce plants of similar types.
