Which statement concerning the reproductive cells in the diagram below is correct?
alexandr1967 [171]

The gametes that are produced contain half the actual number of chromosomes that are found in the organism.

Option C

<h3><u>Explanation:</u></h3>

The gametes are the units of sexual reproduction. These gametes are formed from the gamete mother cell by the process of meiosis. Meiosis actually convert a diploid cell into a haploid cell by reducing the chromosome number to half. So the genetic information of the gamete is also half to that of the other cells of that organism.

When two gametes fuse, they actually complete the full set of chromosomes and form a new organism which contains the characters according to the dominant and recessive basis. So offsprings are not completely similar to any of the parents.
