The Process by Which Gametes Have Their Chromosome Number Reduced

Question

The process by which gametes have their chromosome number reduced by half is called
A) mitosis
B) crossing-over
C) meiosis
D) linkage

Accepted Answer

Meiosis is the process by which gametes (sperm and egg cells) are formed with half the number of chromosomes as the parent cell. During meiosis, there are two rounds of cell division, resulting in four haploid cells with different combinations of chromosomes. Mitosis is a process of cell division that results in two identical daughter cells with the same number of chromosomes as the parent cell. Crossing-over and linkage are processes that occur during meiosis and involve the exchange and inheritance of genetic information between homologous chromosomes.
