Meiosis and Reproduction

    Cards (17)

    • 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
