Heredity

Study Guide

Be sure to understand the following biology terms.  By defining these terms in your own words and by giving an example of the following terms you will begin to understand their meaning.  (Example:  a stimulus is a change in environment or anything a living thing responds to.  An example of a stimulus is a loud noise.)

Biology IH & Biology I

  • Heredity

  • Genetics

  • Gregor Mendel

  • Dominant

  • Recessive

  • Gene

  • Allele

  • Trait

  • True breeding

  • Self pollinating

  • Hybrid

  • Purebred

  • Homozygous

  • Heterozygous

  • P, F1, F2 generations

  • Genotype

  • Phenotype

  • Homozygous dominant

  • Homozygous recessive

  • Punnett square

  • Probability

  • Monohybrid cross

  • Dihybrid cross – indepth Bio IH

  • Trihybrid cross – Bio IH only

  • Test cross

  • Polygenic inheritance

  • Incomplete dominance

  • Multiple alleles

  • Codominance

  • Autosomal dominance genetic disorders

  • Autosomal recessive genetic disorders

  • Sex linked disorders

  • Genetic engineering issues – cloning, stem cells, DNA fingerprinting, gene therapy, GM foods (transgenics), bioremediation, selective breeding, human genome project

  • Pedigree

Be able to answer the following questions thoroughly!

 

  • Describe Mendel’s three laws:  dominance, segregation, independent assortment. – Bio IH only

  • Calculate the genotypic and phenotypic ratios in a dihybrid cross. – Bio IH only

  • Solve Punnett square problems involving incomplete dominance, multiple alleles, autosomal dominance genetic disorders, autosomal recessive genetic disorders, and sex linked disorders.

Remember, any material from past tests is fair game!  This test covers some challenging information.  If you study a little bit everyday, using this study guide,  you will do AWESOME!  Good Luck!
