Vocab Punnett Square: diagram showing possible gene combinations of offspring Probability: likelihood that a particular trait will occur Review… Hybrid: offspring of crosses between parents with different traits Purebred: offspring of crosses between parents with same traits or from asexual reproduction

Mendel’s Laws of Heredity
Rule of Dominance: Some alleles are DOMINANT and others are RECESSIVE An organism with a DOMINANT allele for a particular trait will always exhibit that trait An organism with a RECESSIVE allele for a particular trait will only exhibit that trait if the dominant allele is not present
