Abstract:
Using modern genomic tools, Feng et al. revisited Mendel's seven pea traits in a recent Nature study, uncovering the molecular genetic basis of all of them, including the three unresolved ones: pod color, pod shape, and flower position. Their work highlights the level of complexity provided by structural variation that could impact genes and their regulatory regions and thus influence the expression of plant traits. The authors demonstrate how revisiting foundational experiments with contemporary tools can manifest novel biological insights and also guide future crop improvement.

Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal...
