16 - How many squares in Dihybrid Cross? 20th Century - Golden Age of Genetics 4 - How many squares in Monohybrid Cross? 5 Steps for Punnett Squares - 1.Assign a symbol for each allele 2.Determine the genotype for each parent (diploid) 3.Punnett Square 4.Determine all combinations 5.Determine the phenotype and genotype of each 64 - How many squares in Trihybrid Cross? Alleles - alternative forms of a certain gene Dihybrid Cross - Double Factor Cross Dominant - masks the effects of other alleles (always seen) Drosophilia melanogaster - name for the fruit fly Filial - "F" Gene - a portion of DNA that determines a characteristicGene-chromosome theory - laid the foundation for modern genetic research Genetics - A study of genes, how genes produce characteristics (traits) how traits are inherited Genome - set of all genes necessary to specify an organism's complete list of characteristics Genotype - listing of genes present in an organism (DNA code) /Genetic Makeup Gregor Mendel - Austrian Monk that grew and studied pea plants for 8 years/ Father of Genetics/Father of Heredity/1st to study inheritance of traits and formulate laws Heredity - how traits are transmitted from parents to offspring Heredity Laws - Law of Dominance Law of Segregation-meiosis Law of Independent Assortment-meiosis Heterozygous - two different alleles for a particular trait (carrier) Homozygous - two identical alleles for a particular trait Locus - specific place a gene is located on the chromosome Monohybrid - studying one trait at a time/single factor cross Parent - "P" Phenotype - way the combination of alleles expresses itself. (physical appearance)Punnett Squares - charting device that helps to visualize all possible combinations of genes for offspring Recessive - effect is masked when another allele is present (only seen if individual homozygous is this way) Thomas Hunt Morgan - Proved that genes are a part of chromosomes through his studies with fruit flies/ Chromosomes are the basis of sex determination (1904) Trihyrbid Cross - If both parents are heterozygous for 3 traits Walter S. Sutton - Hypothesized that genes are a part of chromosomes (1902)
