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?

The statement that would be removed and not affect the excerpt's reliability is that unlike heirloom seeds, if one saves a hybrid seed, one will not get the same plant again.

Explanation:

The generation of hybrid seeds takes place by cross-pollination in order to obtain the desired characteristics of both breeds like tolerance to environmental stress, disease resistance, high yield, and others. The removal of the statement unlike heirloom seeds, if one saves a hybrid seed, one will not get the same plant again will affect the dependability of the given verse the least.  

If one saves the hybrid seed then the chances to get the same plant again becomes very uncertain, however, the chances are not nil. They may attain some new favorable features more may even lose some of the features.  

dna damages cause changes in the structure of the genetic material and prevents the replication mechanism from functioning and performing properly. dna damage and mutation have different biological consequences. while most dna damages can undergo dna repair, such repair is not 100% efficient.
