In the C and C++ programming languages, #pragma once is a non-standard but widely supported preprocessor directive designed to cause the current source file to be included only once in a single compilation.
Best Answer: In humans, you would find 23 chromosomes in a sperm cell; 23 chromosomes in an egg cell; and 46 chromosomes in a white blood cell. All human body cells contain 46 chromosomes (two sets of 23 chromosomes). Only the gametes (i.e., the sperm & eggs) contain 23 chromosomes (one set of 23 chromosomes) because two gametes combine to form a new person with 46 chromosomes in his body cells. Body cells grow and reproduce by the process of mitosis.
In meiosis, the chromosome count is reduced from diploid to haploid; the union of two haploid gametes in fertilization restores the diploid chromosome count. Dog sperm contain 39 chromosomes. What are the haploid number and diploid number for dogs. Haploid number (n) is 39; diploid number is (2n) is 78. What process (meiosis or mitosis) is more directly involved in the production of gametes in animals? In plants and most fungi.
