Chromosomal crossover A double crossing over. Chromosomal crossover (or crossing over) is the exchange of genetic material between homologous chromosomes that results in recombinant chromosomes during sexual reproduction. It is one of the final phases of genetic recombination, which occurs in the pachytene stage of prophase I of meiosis during a process called synapsis. Synapsis begins before the synaptonemal complex develops and is not completed until near the end of prophase I. Crossover usually occurs when matching regions on matching chromosomes break and then reconnect to the other chromosome.

F1B English Goldendoodles F1B English Goldendoodle. The backcross (F1B) Goldendoodle is produced by crossing a F1 Goldendoodle with a Poodle (non related of course). F1B Goldendoodles will have a higher success rate for non-shedding, and are recommended for families with moderate to severe allergies. The F1B Goldendoodle is 75% Poodle which makes this generation the most hypo-allergenic of all the English Goldendoodle generations we breed.

Backcrossing Backcrossing is a crossing of a hybrid with one of its parents or an individual genetically similar to its parent, in order to achieve offspring with a genetic identity which is closer to that of the parent.It is used in horticulture, animal breeding and in production of gene knockout organisms.his image demonstrates backcrossing of a heterozygous mouse from one genetic background onto another genetic background. In this example, the gene knockout is performed on 129/Sv cells and then backcrossed into the C57B/6J genetic background.
