Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A somatic cell contains ____
A
Half the number of chromosomes coming from one parent
B
a complete set of chromosomes coming from both parents
Explanation: 

Detailed explanation-1: -In humans, somatic cells are diploid, meaning they contain two sets of chromosomes, one inherited from each parent. DNA mutations in somatic cells can affect an individual, but they cannot be passed on to their offspring.

Detailed explanation-2: -Diploid is a term that refers to the presence of two complete sets of chromosomes in an organism’s cells, with each parent contributing a chromosome to each pair. Humans are diploid, and most of the body’s cells contain 23 chromosomes pairs.

Detailed explanation-3: -In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46.

Detailed explanation-4: -There are 23 pairs of chromosomes in somatic cells; one member of each pair is paternal (from the father) and one maternal (from the mother). There are 22 matched pairs of autosomal chromosomes, plus one pair of sex chromosomes.

Detailed explanation-5: -Each somatic cell in an organism contains the complete set of DNA for that organism. Somatic cells are diploid cells, which means they have two sets of chromosomes where one set comes from the mother and one set comes from the father.
