I believe that the most common antibody switch is from IgM to IgG.
Class switching occurs by a mechanism called the class switch recombination binding. It is a biological mechanism that allows the class of antibody produced by an activated B cell to change during a process known as isotype or class switching. The mechanism changes a B cell's production of antibodies from one form to another, such as from the isotype IgM to the isotype IgG.
Answer:
C) all chinchilla
Explanation:
As we know that dominance of alleles for the coat color in rabbits goes like this:
C+ > Cch > Ch > C.
- The allele for full colour or agouti is designated as C+.
- Allele for mutant coat color silvery- gray coat-chinchilla is Cch.
- Allele for “Himalayan” coat is called ‘Ch
- Albino rabbits have whole white coat and allele for this is c
If we cross homozygous chinchilla with homozygous chinchilla the cross will look like this:
P1: chinchilla x chinchilla
P1: Cch Cch X Cch Cch
F1: Cch Cch : Cch Cch
Since all offspring have Cch Cchgenotype that is foe chinchilla phenotype it means that all the offspring will have chinchilla phenotype that makes option C correct.

The loss of the hydrogen on one molecule produces a negative charge, which is attracted to the positive charge formed by the loss of the hydroxy group from the other molecule.
