[Phenotypic effects of puroindoline gene alleles of bread wheat]
Abstract:
85 winter bread wheat varieties and lines that have been developed mostly in Ukraine were analyzed with NIR for parameters of hardness and protein content. The hardness data were compared with the data of puroindoline gene alleles analysis done earlier and the published data. Significant variation of parameters of hardness was revealed when there was low polymorphism of puroindoline genes indicating the presence of additional genes that influence the hardness parameters.

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 chance to...
