Currently, many heterozygous cucumber hybrids with high yields have been bred. An amateur gardener sowed the seeds of these cucumbers and reaped a good harvest. If a gardener collects the seeds from this crop and uses them to plant the next year, will the harvest be as good? Why?

No, the harvest will not be as good as the seeds are heterozygous, not homozygous, which means there is a gamete in the seed that carries an infertile crop to make it more clear: AA is a homozygote, Aa is a heterozygote, A is a good crop, and a barren crop. Aa x Aa we get the generation: AA (good harvest), Aa (good, but with disadvantages), Aa, aa (bad harvest).
