Punnett Square The alleles of different genes separate independently of one another Heredity Codominance A family history that shows how a trait is inherited over several generations The parental generation - original two individuals that are crossed during a breeding experiment. Homozygous Dominant The physical appearance of a character EX: brown hair, green eyes, etc. Polygenic Inheritance Heterozygous A trait that is determined by a gene found on one of the sex chromosomes, such as the X chromosome. Incomplete Dominance An individual whose phenotype is dominant, but whose genotype is not known, is crossed with a homozygous recessive individual. F2 Generation Alleles A cross that involves ONE pair of contrasting traits. A trait that is not expressed when the dominant trait is present. genes with more than two alleles EX: blood type Probability F1 Generation Genetics
