  • Floyd Zaiger under an aprium hybrid tree. Floyd Zaiger (Born 1926) is a biologist who is most noted for his work in fruit genetics. Zaiger Genetics, located in Modesto, California, USA, was founded in 1958. Zaiger has spent his life in pursuit of the perfect fruit, developing both cultivars of existing species and new hybrids such as the pluot and the aprium. Zaiger under an aprium (apricot & plum) tree- MODEL RELEASED. 1983.

  • A worker emasculates blossoms in the Zaiger's greenhouse. Flower petals and buds are removed to leave the pistol exposed, which is then hand-pollinated with brushes or cotton swabs. Blossoms are collected by hand from specific trees in the orchards and pollen is extracted from them by cutting the flower up with small scissors and sifting the parts. The pollen goes into a small plastic bottle that is numbered and stored in ice chests. Many trees are grown in barrels that are moved into the greenhouse to be worked on or to speed up or slow down pollination and development..Floyd Zaiger (Born 1926) is a biologist who is most noted for his work in fruit genetics.

  • Research on the human genome: Dr Peter Lichter, of Yale Medical School, using a light microscope to do fine mapping of long DNA fragments on human chromosomes using a technique known as non- radioactive in-situ hybridization. The chromosomes appear in red on the monitor screen, whilst the DNA fragments (called probes) appear yellow/green. Mapping chromosomes may be regarded as a physical survey of each chromosome to find the location of genes or other markers. Mapping & sequencing are the two main phases of the genome project; an ambitious plan to build a complete blueprint of human genetic information..Human Genome Project.
