Mendel`s Principles
... One set, or one member of each pair, comes from each parent. Each pair of homologous chromosomes carries genes that govern the same traits. For example, in pea plants, flower color is determined by a single gene F, which can have two different forms, F or f, called alleles. Every cell in the diploid ...
