Question

which consist of sperm cells and egg cells?
gametes
tetrads
diploids
chromosomes

Explanation:

Gametes are reproductive cells. In sexual reproduction, sperm cells (male gametes) and egg cells (female gametes) are involved. Tetrads are structures formed during meiosis (a type of cell division) when homologous chromosomes pair up. Diploids refer to cells that have two sets of chromosomes (most body cells in humans are diploid). Chromosomes are thread - like structures that contain genetic information.

Answer:

gametes
