All but one statement describes an advantage of meiosis.. a). variation is aided by crossing-over which occurs during meiosis.. b). meiosis ensures daughter cells receive one of each kind of gene and half the chromosome number.. c). independent assortment provides a huge number of possible genetic combinations in daughter cells.. d). meiosis occurs often because it allows growth and repair of body tissues in multicellular organisms.

All statements except "D). Meiosis occurs often because it allows growth and repair of body tissues in multicellular organisms" describe the advantages of meiosis.

In multicellular organisms, growth and repair of the tissues are achieved by mitosis.

Mitosis is the process in which parent cell divides into two daughter cells each with the same and an equal number of chromosomes as present in the parent cell.

It helps in producing new cells and replacing the old or damaged cells.

It generally takes place in all the cells of the body (somatic cells) except germ cells.

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.
