Question

As you have determined, the F1 is heterozygous for four loci that affect fruit segment number (A+ A 0B+ B 0C+ C 0D+ D 0). This means that the F1 can produce 16 distinct gamete types, which contain different numbers of additive alleles (designated with the As you have determined, the F1 is heterozygous for four loci that affect fruit segment number (A+ A 0B+ B 0C+ C 0D+ D 0).

F1 hybrids have a very high level of heterozygosity. As a result of this, F1 hybrids display improved growth and yield characteristics."

I'm no expert, but this does not sound quite accurate to me. I can think of a situation where crossing two purely homozygous parent lines will NOT give us a heterozygous F1 generation:

P Generation: aa x aa

F1 Generation = aa

In this situation, crossing two homozygous parent lines has given us a homozygous F1 generation. That parent lines are inbred and homozygous is irrelevant to the fact that the F1 hybrids are heterozygous.

Rather, the heterozygosity of the F1 generation observed in agronomy/hybrid seed production can be attributed to the relative dissimilarity between the two parent types (the less closely related they are, the less chance that multiple copies of the same
