... Mendel’s law applies to two (or more) alleles (alternate forms of a gene). The allele pairs separate in Meiosis I, when a diploid cell divides into two haploid cells, before the formation of gametes. So, for example each sperm or egg will get just one big R, or one little r, or one big T, or one lit ...
