Exam 3 will cover at least chapters 7 and 8; perhaps chapter 9. Make sure to be present for the review session to know what the content will be, and where it will be split - if that is the case.
Read the text, so that you have the proper context for the material covered on the exam.
Do not be late for the exam, since by being late you might not be able to take the exam and your grade might be seriously affected.
Some of the questions below apply to the
material that will be on the exam.
These are general questions that are open-ended, meaning
that the more that one can answer on any specific question, the
better-prepared one should be.
From chapter 9, know what are genes and what are alleles? What does purebred or true-breeding mean? What was the general nature of Mendel’s breeding program, in terms of Parent crosses, F1 hybrids, F1 crosses, and F2 hybrids? What are monohybrid and dihybrid crosses? What were the typical ratios Mendel observed in the F1 and F2 offspring of his mono- and dihybrid crosses? Be able to define and understand the terms dominant, recessive, genotype, phenotype, homozygous, and heterozygous. What is the law of segregation? The law of independent assortment? Know how to predict offspring phenotypes and genotypes from simple crosses. Know about “carriers”, codominance, incomplete dominance, multiple alleles, multiple genes or polygenics, gene linkage, and sex chromosome inheritance (sex linkage).
