Homologous chromosomes mean that diploid cells have two copies of each gene, with one copy coming from mom and one copy coming from dad!
- However, the sequences of the two genes do not have to be identical
Genes - small fragment of DNA in a chromosome where a piece of genetic (hereditary) info is stored - gene locus = place on the chromosome where the gene resides; controls a particular trait e.g. colour, height, etc.
