Grade 11-SBI3U Biology Mendelian Genetics Miss Jessica Fricker, October 2024 Minds On Q. Do plants have sperm and eggs? Minds On Minds On Gregor Mendel This guy here is considered the father of modern genetics (pretty snazzy, no?) He’s also a monk Gregor Mendel He is considered the father of modern genetics BECAUSE he developed ideas of: SEGREGATION: chromosomes are split in meiosis RECOMBINATION: chromosomes come from both the mother and the father INDEPENDENT ASSORTMENT: I hope you remember what this is DOMINANCE you’ll find out what this is Gregor Mendel’s Predecessors Preformationists vs Epigenesists Gregor Mendel’s Predecessors Mendel disproved this using..... Gregor Mendel Gregor Mendel Gregor Mendel He called traits that masked other traits DOMINANT Gregor Mendel Traits that were overpowered, or covered up, were called RECESSIVE Gregor Mendel Two “characters” influence each trait One from Mother, one from Father Gregor Mendel Two “characters” influence each trait One from Mother, one from Father Gregor Mendel Two “characters” influence each trait One from Mother, one from Father Heterozygous Homozygous Dominant Homozygous Recessive Gregor Mendel Two “characters” influence each trait One from Mother, one from Father Heterozygous Homozygous Dominant Homozygous Recessive Gregor Mendel Two “characters” influence each trait One from Mother, one from Father Heterozygous Homozygous Dominant Homozygous Recessive Gregor Mendel Two “characters” influence each trait One from Mother, one from Father Gregor Mendel Two “characters” influence each trait One from Mother, one from Father Gregor Mendel Two “characters” influence each trait One from Mother, one from Father Gregor Mendel YOUR TURN TO MAKE A PUNNET SQUARE: Is the dominant parent HOMOZYGOUS or HETEROZYGOUS? C) What are the offspring ratios? Gregor Mendel YOUR TURN TO MAKE A PUNNET SQUARE: Is the dominant parent HOMOZYGOUS or HETEROZYGOUS? C) What are the offspring ratios? Exit Ticket: Mendelian Genetics Summarize the main points of today’s lesson with a drawing or a diagram. Be sure to annotate it properly! Gregor Mendel: vocabulary Heterozygous: (Pp) a set of alleles with one dominant and one recessive gene Homozygous: (PP) or (pp), when both alleles carry the same genetic marker Homozygous Dominant: (PP) both genes are dominant Homozygous Recessive: (pp) both genes are recessive Dominant: The trait that generally overpowers the other trait, the one that presents itself when two different traits are crossed Recessive: The trait that “disappears” when two different traits are crossed Testcross: The hypothetical offspring of two specimens F1: The first generation of offspring in a testcross, the “children” F2: The second generation in a testcross, the “grandchildren” Allele: a piece of DNA that codes for a particular gene, or trait. Mendel’s “characters” Genotype: The genetic code that contains both traits inherited from your father and mother. These traits may not be the same Phenotype: The physical appearance of the specimen; the genes that are expressed Punnett Square: a diagram that is used to help predict the genotypes of offspring from a testcross Monohybrid cross: The testcross of two parents who differ in one trait only (ie. colour, height, pea pod shape)
