Somatic Recombination In a world filled with viruses and bacteria all out to kill us, the human immune system has to have a way to defend our bodies It has antibodies, created in the B-lymphocyte white blood cells o Antibodies are Y-shaped glycopro

Usually crossing over is thought of as occurring only in meiosis in order to create more variation in the gametes. While crossing over does occur in meiosis, it will occasionally occur in mitosis.

Mendel discovered that all of these genes were diploid Mendels Rules: 1. Rule of Segregation a. From an individual diploid they will donate one or the other allele b. Alleles segregate 2. Rule of Independent Assortment a. All

Investigating Allelic Relationships Using Genetic Complementation.
The phenotypic variations of a given population can be due to several mutations.
Geneticists have devised a way to understand
