Uniformity rule (1st Mendelian rule)


Definition and example - easily explained

According to the rule of uniformity, the offspring of a homozygous (homozygous) race of the parental race, which differ in only one trait (for example, color - one flower red, the other white), are always uniform. Accordingly, it means having the same phenotype.
at dominant-recessive inheritance If only one gene prevails, in this example (see picture) the color is red dominant. The genotype of branch generation1 consists of one dominant gene R and one recessive gene w for each flower. Consequently, the dominant R prevails and the flowers both turn red.
in case of an Intermediate inheritance all flowers of the branch generation1 would form a mixed form, since neither R nor w would be dominant.
