Concern 34. Create an email on mind fertization. Answer: > (dos Scratches) Fertilisation for the an extract otherwise creature by mix of male and you will girls gametes developed by an identical personal (or) > (3 Scratching) Fertilisation that occurs when male and female gamete developed by brand new system unite notice fertilisation take place in many protozoans and invertebrate animal.
