The Work of Gregor Mendel
... Where two or more alleles for a gene exist, some may be dominant and others recessive. In sexually reproducing organisms, offspring receive a copy of each gene from each parent. The alleles segregate when forming gametes. Alleles for different genes usually segregate independently. ...

Genes
... Mendel as affecting seed forms (rounded vs. wrinkled, see Fig. 1.4) consists of 3546 bp. The whole pea genome is about 4 300 x 106 bp, thus roughly estimating, a DNA molecule may contain about million different genes. However, it is not a case; genes are often only a tiny proportion of plant genomes ...
