Why should gametes be produced by meiosis during sexual reproduction?
Advertisements
उत्तर
Meiosis is important as it produces gametes i.e., male or female germ cells. During meiosis a germ cell or gamete divides to make four new sex cells. As a result of fertilization two gamates join together to form an egg or zygote. Therefore only if gametes are produced, fertilization can take place
