Individuals have two of each chromosome and hence two alleles of each gene, one acquired from each parent. These versions may be identical or may differ from each other.

We will talk about unisexual and bisexual flowers. The difference between carpel and pistil. The different types of pollination - self and cross pollination - and fertilisation.
