If an egg cell containing the (n+1) number of chromosomes combines with a sperm cell containing the (n) number of chromosomes, what is the result of this union?

The result of the union will be ' All future somatic cells of the organism will contain the (2n + 1) number of chromosomes. '

Explanation:

As we know, fertilization is a process in which the egg cell and the sperm cell join to form a zygote. If an egg cell which contains n+1 number of chromosomes joins with a sperm cell containing n chromosomes, then the zygote formed will have n+n+1 i.e 2n + 1 number of chromosomes.  The zygote  goes through multiple cell divisions to form different cells. All the somatic cells are formed by mitosis. As mitosis produces identical daughter cells hence, all of the somatic cells will have 2n + 1 number of chromosomes.

All future somatic cells of the organism will contain the (2n + 1) number of chromosomes.

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.

the correct answer is b
