Diploid vs Haploid

If every human on earth looked exactly the same, the world would be a boring place. Thank goodness for genes! Pupils explore the difference between haploid and diploid cells by learning how two parents without red hair can produce a child with red hair, exploring the difference between chromosome numbers of haploid and diploid cells, and seeing how haploid and diploid cells form.
