[Hybridization and genetic control of esterase in apricot]
Abstract:
Inheritance of esterase was studied in nine segregating progenies. It was established that fast migrating components are controlled by two loci, Est-1 (monomeric alpha-esterase) and Est-2 (dimeric beta-esterase). Their polymorphism is determined by three active alleles, a, a', b for Est-1 and a, b, c for Est-2, respectively. Allelic frequencies and heterozygosity of loci in ecological-geographical groups and Central Asian subgroups were estimated. Genetic control of esterase in stone fruits was proposed for the first time.

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...
