what is sexual reproduction
the fusion of male and female gametes
features of sexual reproduction
there is variation in offspring and involves meiosis
features of asexual reproduction
involves one parent which leads to no variation [clones]. only mitosis involved
what is meiosis
the process of halving chromosomes in gametes before reproduction
where does meiosis take place?
in reproductive organs in which they divide to make gametes

how do the new cells divide?
mitosis
what happens as the number of cells increase
the embryo develops and cells differentiate
