<h3>What is speciation?</h3>

Speciation is the evolutionary process in which in populations of organisms come to being or evolve to become distinct species. The biologist Orator F. Cook made some Discovery and term it speciation in 1906when he performed experiment on cladogenesis, the splitting of lineages, as opposed to anagenesis, phyletic evolution within lineages.

The immunoglobulin light chain does not have a D segment. In humans, there are two different possible light chain proteins, term
wlad13 [49]

Answer:

295  

Explanation:

Antibodies (also known as immunoglobulins) are immune system-related proteins that circulate in the bloodstream in order to recognize pathogenic harmful substances (antigens) and neutralize them. An antibody consists of two immunoglobulin heavy chains and two immunoglobulin light chains. There are two types of immunoglobulin light chains: 1-the kappa (κ) light chain, which is encoded by the immunoglobulin κ locus; and 2-the lambda (λ) light chain, which is encoded by the immunoglobulin λ locus. The immunoglobulin light chain is a multidomain protein composed of two domains: 1- the N-terminal variable (V) domain and 2-the C-terminal constant (C) domain. V(D)J recombination is a type of somatic rearrangement process by which T and B cells can assemble different gene segments, which are referred to as variable (V), diversity (D) and joining (J) gene segments. In the question above the number of possible genomic recombination events between immunoglobulin gene segments can be calculated as >> (5 x 35) + (4 x 30) = 295.
