Meiosis and Reproduction

• What is the male gamete in animals

  sperm
• What is the female gamete in animals

  Egg
• What name can be given to cells resulting from asexual reproduction?

  clones
• Fertalised eggs have the correct number of chromosomes because gametes only have half the number of chromosomes of a normal cell, so when two gametes fuse together, the fertalised egg has the full number of chromosomes
• Asexual reproduction only involves one parent, whereas sexual involves two
• There is no fusion in gametes in asexual reproduction
• There is no mixing of chromosomes in asexual reproduction
• Asexual reproduction doesnt involve meiosis
• What happens do DNA at the very start of meiosis?

  It is duplicated
• How many cells are there during the process of meiosis?

  2
• Meiosis:

  Four gametes are produced, each with a single set of chromosomes. Each of the gametes are genetically different from the others.
• What happens to the cells in the embryo as they develop?

  They differentiate into different types of specialised cell
• Some organisms reproduce both sexually and asexually. For example, strawberry plants reproduce asexually using runners and reproduce sexually by producing seeds.
• What type of reproduction is shown when the bulbs divide to produce new plants?

  Asexual
• Malaria parasites reproduce asexually in the human host, but sexually in the mosquito
• Asexual reproduction uses less energy because organisms dont have to find a mate
• Asexual reproduction is faster
