Mendelian principlesThe three “laws” delineated by Gregor Mendel, which form the basis for understanding single trait inheritance.
Principle of uniformity in F1
In a mating between a parent with a dominant phenotype (due to homozygosity of an allele) and another parent with a homozygous recessive phenotype controlled by a different allele at the same locus, the progeny will all be genetically heterogeneous and express the dominant phenotype.
Principle of segregation
The principle that holds that alleles separate or segregate at meiosis and are carried in different gametes.
Law of segregation
The principle that holds that allelic pairs of unlinked loci are independently sorted and transmitted to gametes.
