Basic Concepts of Proteomics: The gene transcripts that an individual can make in a lifetime—termed as transcriptome (by analogy with the term genome)—refers to the haploid set of chromosomes carrying all the functional genes. Mosaicism is a condition where an individual’s cells are genetically variegated. SOMATIC SEGREGATION When an organism produces several types of offspring the nor mal moment of segregation is at the reduction division, in which case segregation usually obeys Mendel's laws. Mosaicism describes an individual composed of two or more genetically different populations of cells existing side by side within the skin. You can change your ad preferences anytime. M.H. • In 1936, he demonstrated that recombination, normal in meiosis, can also take place in mitosis. This is a disorder that causes red, scaly skin all over the body. With the advent of individualized whole-genome sequencing in the past decade, it has become obvious that each individual has its own genetic constitution comprising thousands of SNPs and copy number variations, most of which are apathogenic. Similarly, all the proteins made by […] See our Privacy Policy and User Agreement for details.

Mosaicism can cause many different kinds of disorders, such as: Ichthyosis with confetti. In a normal cell, the concentrations of active (dephosphorylated) merlin are controlled by processes such as cell adhesion (which would indicate the need to restrain cell division). In genetics, a mosaic, or mosaicism, involves the presence of two or more populations of cells with different genotypes in one individual who has developed from a fertilised egg.
