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