• Asexual need one parent only
• Sexual reproduction needs two parents
• In sexual reproduction, the offspring will have different combinations of genes from both parents.
• The process of fertilisation is when sperm meets egg to form zygote
• In sexual reproduction the offspring are genetically different from their parents
• In asexual reproduction, the offspring are identical to their parents
• The advantage of asexual reproduction is that it can produce many offspring quickly
• Zygote divides into embryo which develops into foetus
• During mitosis, cells divide into identical daughter cells
• Zygotes are formed by fusion of gametes (egg + sperm)
• In asexual reproduction the offspring are identical to their parents
• Fertilization occurs inside the female body
• Gamete = sex cell
