Chimeras are interesting organisms that have two different sets of dna. chimeras occur when two different zygotes fuse to form one organism. some chimeras have no outward symptoms, while some have signs such as two different eye colors or two different blood types. this model shows how chimeras form. what roles do mitosis and meiosis play in the process?

meiosis creates haploid sperm and an egg that fuse to form two zygotes. they then fuse together into a single embryo, and the process of mitosis allows the cells to divide. this process creates an embryo that has two different types of genetic material

Explanation: plato answer but slightly worded differently

Meiosis creates haploid sperm and an egg that fuse to form two zygotes. When the zygotes fuse into a single embryo, the process of mitosis allows cells to divide. This process creates an embryo that has two different types of genetically material.

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.
