Genetics; Part 1-Classical Genetics to Monohybrid Crosses

Author: Bob Grove
Description:

Part 1 of our unit on genetics looks at the work of Gregor Mendel and how our inherited traits come from the genes of our parents.

Part 1 covers pages 263 to 269 in your text book; from a discussion of traits through Mendel's experiments.

Tutorial

Our First Lesson

Our first lesson is a powerpoint on fundamental genetics. It looks at the meaning of words like traits, and heredity.

We start with the work of Gregor Mendel that lead us to today's understanding of genetics. A lot of important terms are discussed in this lesson and you need to know them:

  • traits
  • heredity
  • genetics
  • self-pollinate
  • cross-pollinate
  • cross
  • true breeding
  • hybrids
  • dominant
  • recessive
  • genes
  • alleles
  • P generation
  • F1 generation
  • F2 generation
  • gamete
  • Principle of Segregation
  • genotype
  • phenotype
  • punnett square
  • homozygous
  • heterozygous
