Question

what is true breeding? letting plants reproduce with plants of other genotypes to enhance genetic diversity allowing a plant to self - pollinate so that it will produce offspring identical to itself letting plants reproduce with plants of other genotypes to produce identical offspring

Explanation:

True - breeding refers to organisms that, when self - pollinated or self - fertilized (in the case of plants), produce offspring that are genetically identical to the parent. This is because true - breeding organisms are homozygous for the traits in question. When a plant self - pollinates and produces offspring identical to itself, it is a true - breeding plant. The first option about enhancing genetic diversity is incorrect as true - breeding does not enhance genetic diversity. The third option about reproducing with other genotypes to produce identical offspring is also wrong because true - breeding for identical offspring occurs through self - pollination (or self - fertilization in some cases), not by crossing with other genotypes.

Answer:

allowing a plant to self - pollinate so that it will produce offspring identical to itself
