Question

Gametes formed by meiosis are called as
A. Coenoga metes
B. Meiogametes
C. Mitogametes
D. None of the above

Answer 1

Hint: In eukaryotes, two types of cell division occurs i.e. Mitosis and meiosis. In mitosis, the parent cell divides into two daughter cells and each receives an exact copy of the chromosome in the parent cell. In Meiosis, the genetic material in the daughter cell is reduced to half that of the parental chromosome number so that fertilization will restore the diploid complement.

Complete answer: In meiosis, the number of chromosomes is reduced to half. The reduction in chromosome number is attained by one round of DNA replication and is followed by two rounds of chromosome segregation. Meiosis occurs in two stages i.e. meiosis I and meiosis II. At the end of meiosis four daughter cells are formed unlike that of two daughter cells at the end of mitosis. Each daughter cell in meiosis has one half of the number of chromosomes as the parent cell. Daughter cells formed at the end of meiosis are called meiogametes. In some lower organisms, spores formed by meiotic division are called meiospores.
So, the correct answer to the given question is option B, i.e., Meiogametes

Note: Meiosis is called a reductional division and mitosis is called an equational division. Mitotic division occurs in the somatic cell and hence called somatic cell division. Meiosis occurs in germ cells that produce gametes. In meiosis haploid state is attained to maintain the diploidy of the organism at the time of fertilization.
