Question
State any three characteristics of sexual reproduction.
✓
Answer
- Two different sexes i.e., male and female take part in the process.
- Testis in male produces the male gametes or sperms and the ovary in female produces female gametes or ova.
- Gametes are formed by meiosis or reduction division and so are haploid in nature.
- Sperms are motile and move towards ovum for fertilisation.
- Sperms and ova come into contact with each other and fuse to form a zygote or egg by a process called fertilisation.
- It involves slow multiplication.
- Variations appear due to new combinations of genes during crossing over.
- Daughter organisms or offsprings are genetically different from the parents.
- The diploid zygote then divides by mitosis and passes through different develomental phases to transform into a multicellular individual.
