1. Do you find it interesting that Mendel used just one letter for homozygotes (e.g. A) but two letters for heterozygotes (e.g. Aa)? 2. I didn\'t know Mendel bred his plants to the F6 generation - what do you think about the work that would have gone into running so many generations? Solution 1. Do you find it interesting that Mendel used just one letter for homozygotes (e.g. A) but two letters for heterozygotes (e.g. Aa)? Homo - same Hetero - Different If you take any dipoloid organism, those have two similar sets of chromosomes. If you take any gene, there is a possbility of two alleles. If those alleles are same in their configuration, those are called homozygotes, if those are different in their configuration those are called heterozygotes. Eg. For gene A, Homozygours dominant genotype: AA Homozygous recessieve genotype : aa Heterozygous genotypes : Aa.
