PPT-Dominant/Recessive Patterns of Inheritance and Punnett Squa

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 DominantRecessive Pattern. This presentation . builds on session 1 exploring patterns of inheritance. Patterns of inheritance. The objectives of this presentation are to:. Understand how genes are inherited. Understand the differences between the inheritance patterns associated with Autosomal dominant, Autosomal recessive, X-linked recessive and chromosomal abnormalities. Assortment. 2015 – 2016. Biology/Biology Honors. Ms. McCabe. Do Now 1/12-13/16. In 1 complete paragraph, on a half-sheet of paper, answer the following for your class:. Periods 1 & 6: . What are factors that might affect the rates of photosynthesis & cellular respiration?. 1/21. Set up Quarter 3 INBs today!!!. Qtr.3 Materials will be checked . tomorrow.

These are some of the common dominant and recessive traits in humans that can be easily observed in people around you. . You . have two genes for them. One inherited from your father and one from your mother. The way that a physical trait is expressed, and hence the way you look is a result of either a combination of dominant genes, a dominant and a recessive gene or two recessive genes.. Compiled by: . Hailey . Haberman. Mendel’s Law of Inheritance. Genotypes, Phenotypes & Punnett Square. Objectives:. Explain . Gregor. Mendel’s laws of inheritance . Discuss the difference between genotypes and phenotypes. Chapter 4 Sections 1and 2. Parents and offspring are similar.. We all have our own unique combination of characteristics. These are called traits. There are two types of traits:. Inherited traits resemble those your birth parents have, like hair color, eye color, blood type.. . . - . Each individual gets ½ of their genetic information from their mother and ½ of their genetic information from their father. Punnett. Squares are a quick and easy way to determine what the offspring (children) will look like. 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 . 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. Staring 3 dogs and 3 cats. Terminology. Genes- Basic unit of hereditary, sequence of nucleotides on a chromosome that encodes a protein. Alleles- Alternate forms of a gene. Genotype- Allele combinations. Definition . Allelle. is . an alternative form of a . gene . (one member of a pair) that is located at a specific position on a specific . chromosome. . These DNA coding . determine distinct traits that can be passed on from parents to offspring. . Genetics. Genetics. is the study of inheritance of genes. . i.e. genetics is how traits are passed down from parents to offspring . Every individual offspring inherits at least two copies of every gene – one from the mother and one from the father. . Why do we look the way we do?. . All organisms are made of cells.. Inside of these cells, a chemical called DNA contains the “instructions” that control the way we look.. DNA. DNA: the instruction manual. Sheep, goats, and the octopus have almost rectangular-oval pupils in their eyes. .. Content Objective. : . I will understand and predict genetic outcomes using a . Punnett. Square.
