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