WebThe 3 principles of Mendel’s laws of genetics are the law of dominance, the law of segregation and the law of independent assortment. The law of dominance stated that in a heterozygous condition, the dominant allele will dominate over another allele. This means that the dominant trait or phenotype will be present. WebMendel's First Law - the law of segregation; during gamete formation each member of the allelic pair separates from the other member to form the genetic constitution of the gamete Confirmation of Mendel's First Law Hypothesis With these observations, Mendel could form a hypothesis about segregation.

WebMendel’s laws (principles) of segregation and independent assortment are both explained by the physical behavior of chromosomes during meiosis. Segregation occurs because each gamete inherits only one copy of each chromosome. Each chromosome has only one copy of each gene; therefore each gamete only gets one allele.
