PPT-Punnett Squares Day 2 Complex Patterns of Inheritance

BELL RINGER 5 MIN Two parents are heterozygous for a given trait What percentage of the offspring of the two parents will be homozygous for the same trait Have homework out and ready to turn . Punnett Squares Notes representing the possible comb inations of alleles from the parents. It was then possible to predict the possible outcomes of the offspring. Before taking a closer look at Pu 1/21. Set up Quarter 3 INBs today!!!. Qtr.3 Materials will be checked . tomorrow. New Notebook (70 page spiral). Highlighter. Glue Stick or Tape. Colored Pencils. Set up new Qtr.3 notebook today. Pg.1= Student info page . Essential Questions. 1. What is the difference between genotype and phenotype?. Give an example of a genotype and a phenotype.. 2. What does it mean if an organism is homozygous?. 3. What does it mean if an organism is heterozygous?. Squares. Step-by-Step Overview. Genetics Problems: . Punnett. Squares. When we have enough information about two parent organisms, we can predict the genotype and phenotype of their . offspring. Genetics Problems: . Incomplete/Codominance. So far, we have learned about simple . Mendelian. inheritance-. -traits controlled by dominant and recessive paired alleles. However, MOST alleles are not simply dominant or recessive. Pattern of Inheritance. a . description of how contrasting genes on homologous chromosomes interact with one another. when . two alleles are different, how do they affect the . phenotype. Dominant/Recessive Pattern. Making Genetic Predictions. Mendel found that you could predict the. traits . of a percentage of the offspring.. . He invented and used the tool of a . Punnett. square . to illustrate these percentages.. Punnett Squares . To help explain how alleles were separated into gametes and rejoined, . Reginald Punnett . developed a visual tool to depict test crosses and show the offspring’s possible genotypes and phenotypes . Incomplete/Codominance. So far, we have learned about simple . Mendelian. inheritance-. -traits controlled by dominant and recessive paired alleles. However, MOST alleles are not simply dominant or recessive. Create a Venn diagram comparing phenotype and genotype: Use the . words physical appearance, genetic makeup, heterozygous, homozygous, describes an organism, purple, tall, Pp, green,pp. Describe the difference between complete dominance, incomplete dominance, and codominance. Chapter 12. I. Pedigree. Graphic representation of genetic inheritance. (Look at Fig 12.1 and 12.2). I. Pedigree. Circle = female. Square = male . Shaded = shows trait being studied. Half Shaded = Carrier. Create a Venn diagram comparing phenotype and genotype: Use the . words physical appearance, genetic makeup, heterozygous, homozygous, describes an organism, purple, tall, Pp, green,pp. Describe the difference between complete dominance, incomplete dominance, and codominance. Mendel Notes. Kahoot. Monohybrid and Dihybrid Punnett squares. Quizlet Live. I can…. Describe Mendel’s study and conclusion of inheritance in peas.. Explain the principle of dominance.. Define heterozygote and homozygote.. One allele from a female egg is joined with one allele from a male sperm.. Probability and predicting inheritance. Since alleles for a trait separate during meiosis, we can use the laws of probability to predict genetic outcomes..
