(Note that a third model of recombination, synthesis-dependent strand annealing [SDSA], has also been proposed to account for the lack of crossover ... that homologous chromosomes reside in ...

This means that all the offspring produced will be tall. In this genetic cross, Parent 1 is still tall but is heterozygous with alleles Tt. Parent 2 is short and is homozygous with alleles tt.

“Second, the genetic diversity of the crop is much lower ... and the new Seed Finder system that finds any variety’s cross-matches, need to join FBN for $600 per year and submit at least ...
