Answer:
Heterozygous = When the offspring inherits two different alleles
Probability = The mathematical chance that something will happen
Trait = Characteristics of an organism that makes it unique
Dominant = The allele that always shows up and hides the weaker allele
Recessive = The allele that is always masked in the presence of the stronger allele
Heredity = The passing of traits from parent to offspring
