The scientific study of biological inheritance
Genetics
Process in sexual reproduction in which male and female reproductive cells join to form a new cell
Fertilization
Specific characteristic of an individual
Trait
Offspring of crosses between parents with different traits
Hybrid
Sequence of DNA that codes for a protein and thus determines a trait
Gene
One of different forms of a gene
Allele
Mendel’s second conclusion, which states that some alleles are dominant and others are recessive
Principle of Dominance
Separation of alleles during gamete formation
Segregation
Sex cell
Gamete
the likelihood that a particular event will occur
probability
Having 2 identical alleles for a particular gene
Homozygous
Having 2 different alleles for a particular gene
Heterozygous
Physical characteristics of an organism
Phenotype
Genetic makeup of an organism
Genotype
Diagram that can be used to predict the genotype and phenotype combinations of a genetic cross
