3 Reproduction Flashcards
What is asexual reproduction?
Involves one parent and offspring have identical genes to the parent - so no variation in parent and offspring
What is sexual reproduction?
Involves the fusion of male and female gametes. offspring have a mixture of their parents genes
What type of reproduction is common in bacteria?

What type of reproduction do plants do?
both
What type of reproduction do most animals do?
sexual
What type of reproduction needs two parents?
sexual
What type of reproduction needs only one parent?
asexual
What type of reproduction are gametes made?
sexual
What type of reproduction involves cell fusion?
sexual
What type of reproduction involves no cell fusion?
asexual
What type of reproduction creates a variety in offspring?
sexual
What type of reproduction creates clones in offspring?
asexual
What cell division produces genetically identical cells?
mitosis
What cell division produces gametes?
meiosis
What is fertilisation?
the fusion of the male and female gamete forming a zygote
What cell division does a zygote undergo?
mitosis to produce all cells which will make up an adult. All these cells must have the full (diploid) number of chromosomes, so the zygote divides repeatedly and develops into an embryo
