Chromosomes, Genes & DNA - Coggle Diagram

- - - - product of sexual reproduction and so inherit 1 of each chromosome from your mother and 1 of each pair from your father
      - 2 sets of chromsomes
        
        diploid
        
        humans, animals and many plant cells are diploid
        
        :star: diploid = having 2 copies of each gene
        
        these don't have to be the same as each other though because you inherited 1 copy from your mother via the egg and 1 from your father via the sperm
  - - - ~20,000 genes in the human genome
        
        each chromosome has hundreds of genes along its length
    - - the combination of alleles (genes) that is inherited will determine the characteristics that are expressed
        
        many genes work together to give a particular characteristic: skin colour is an example of this where there are many different genes that affect how much melanin your skin will produce
