Study Guide: Mendel and Meiosis

Discuss why Mendel used peas, successfully, for his studies of             heredity.

Define heredity, genetics, traits, cross.

Describe

• A monohybrid cross - how it is done, the generations involved, and the results that can be expected based upon the parental    genotype (ideally using

Mendel's monohybrid cross)

Define dominant, recessive, genotype, phenotype, homozygous, heterozygous

Describe

• How phenotype reflects genotype

• Know the proper way to write the symbols for dominant and recessive alleles
• Describe the Laws of segregation and independent assortment
• Describe a dihybrid cross - how it is done, the generations involved, and the results that can be expected based upon the parental genotype (ideally using Mendel's dihybrid cross)

• Predict the offspring of any monohybrid or dihybrid cross using the Punnett square method

Define haploid and diploid

• know which cells in your body   are which

Describe

• The process of meiosis- why is it necessary, how is it accomplished, what the result of it is, where it occurs, etc....

Describe

• What would happen if the cells used in sexual reproduction were the product of mitosis.
• Compare and contrast meiosis and mitosis.
• Explain the two ways in which genetic variation arises as a result of meiosis.
• How does meiosis explain Mendel's results?

Define aneuploidy, trisomy, monosomy, triploidy, nondisjunction.

• Be able to briefly discuss the chromosomal abnormalities that we  covered.
