If 2n=46 for a particular cell, then the chromosome number in each cell after meiosis would be a. 92
b. 46
c. 23
d. 6
e. none of the above

C. 23

Explanation:

In humans (2n = 46), who have 23 pairs of chromosomes, the number of chromosomes is reduced by half at the end of meiosis I (n = 23).

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
