Matching Pairs Mendel Genetics VocabOnline version Genetics vocabulary words and examples by alicia ussery 1 Multiple alleles 2 Law of Independent Assortment 3 Law of Segregation 4 The passing of characteristics from parents to offspring 5 The different versions of a gene 6 Phenotype 7 The offspring of the P Generation 8 Monohybrid Cross 9 When two dominate alleles are expressed at the same time 10 Test Cross 11 A characteristic of an organism that is determined by many genes 12 The displaying of a phenotype that is intermediate (a mix) between parents. 13 Two different alleles of a particular gene present in an individual EX- Rr 14 The offspring of the F1 Generation 15 the science of heredity - traits are passed down from parents to offspring 16 A diagram that predicts the outcome of a genetic cross 17 The likelihood that a specific event will occur 18 P Generation 19 Recessive 20 Two of the same alleles of a particular gene present in an individual EX: RR, rr 21 Pedigree 22 Sex-Linked Gene 23 The expressed form of the allele. F2 Generation genes with more than two alleles EX: blood type A trait that is determined by a gene found on one of the sex chromosomes, such as the X chromosome. Probability Two alleles for a character segregate when gametes are formed. Homozygous Punnett Square An individual whose phenotype is dominant, but whose genotype is not known, is crossed with a homozygous recessive individual. A cross that involves ONE pair of contrasting traits. Heterozygous Dominant Codominance The parental generation - original two individuals that are crossed during a breeding experiment. Polygenic Inheritance The alleles of different genes separate independently of one another Alleles F1 Generation Incomplete Dominance Heredity Genetics A trait that is not expressed when the dominant trait is present. A family history that shows how a trait is inherited over several generations The physical appearance of a character EX: brown hair, green eyes, etc.
