3.1 understand the difference between sexual and asexual reproduction

Asexual reproduction (e.g. flowering plants) involves one parent and mitosis (cell division where the cell reproduces itself by splitting to form two genetically identical cells with identical sets of chromosomes), sexual reproduction (e.g. humans) involves two parents and meiosis (cell division producing 4 haploid cells that are not identical).

Definitions for exam...

Asexual reproduction involves only one parent. The offspring have identical genes to the parent, so there is no variation between parent and offspring.

Sexual reproduction involves the fusion of male and female gametes. Because there are two parents, the offspring contain a mixture of their parent's genes.

  1. good that we have asexual reproduction as there are less bees year by year as well as other pollinating insects - otherwise we would be soon starving
