Boveri-Sutton chromosome theory

Boveri worked with sea urchins; Sutton worked with grasshoppers. Both proposed that chromosomes are responsible for Mendelian inheritance. Boveri showed that all chromosomes were needed for embryonic development. Sutton showed that each offspring inherits half its chromosomes from each parent.

Meiosis and synapsis

Meiosis and synapsis— cell division producing germ cells an egg and a sperm each with half the chromosomes of each parent and pseudo-reduction occuring after fertilization when the chromosomes of egg and sperm get together.

Meiosis dance

Grab your partners chromosomes, move to opposites centrioles, dissolve oh nucleus your membrane, chromatids, chromatids to the center, chromatids, chromatids all line up, attach to the left, attach to the right then pull apart, all pull apart, divide the cell, divide the cell, and each divided half divide.

From the 1890s, many scientists, working independently, rediscovered and advanced Gregor Mendel’s work on the laws of inheritance and began to tease out the mechanisms behind it. In addition to Theodor Boveri and Walter Sutton, the scientific historian should study the work of Hugo de Vries, Erich von Tschermak, Carl Correns, and William Jasper Spillman.
