What is the genetic complement of all cells in the human body,except sex cells
A) 23 chromosomes
B) 46 chromosomes
C) 23 recessive genes and 23 dominant genes
D) 46 pairs of chromosomes
Genetic Complement
The full set of genes or genetic material present in a cell or organism, contributing to its characteristics and traits.
Sex Cells
Reproductive cells (also known as gametes) that contain half the genetic material of an organism and unite during fertilization to form a new organism.
- Present the basic tenets of genetics, emphasizing genotype and phenotype, and the contributions of chromosomes and genes to genetic makeup.

Final Answer :
B
Explanation :
The genetic complement of all cells (except sex cells) in the human body is 46 chromosomes (23 pairs). This includes two copies of each chromosome - one inherited from each parent. Choice A (23 chromosomes) is incorrect because that is the number of chromosomes found in sex cells (sperm or egg). Choice C (23 recessive genes and 23 dominant genes) is incorrect because genes are not always dominant or recessive, and the genetic complement of an individual's cells would not be described in terms of dominant/recessive genes. Choice D (46 pairs of chromosomes) is incorrect because while it is technically true that there are 46 pairs of homologous chromosomes in each cell (excluding sex cells), it is more commonly stated that there are 23 pairs of chromosomes.
