explain the important features of Mendel’s experimental design?
Single gene Mendelian inheritance patterns: if you are told the phenotype of the parents and whether the trait is dominant or recessive etc, be able to predict the genotype of the children. If you are told the phenotype of the parent as well as the inheritance pattern, be able to predict the parent’s genotype.
Be able to set up and use a Punnett square to solve problems and make predictions.
Be able to explain the major steps in how information from our genes is used to make proteins. Or to show it in a labeled diagram.
Be able to explain whatis transcription, translation. Where in the cell do these processes occur? In what order? What type of molecules are being made [DNA, RNA, protein]? What are their building blocks?
What is a mutation? How can a mutation in DNA cause a change in a protein? (use the following terms to answer: codon, transcription, translation, mRNA).
What is gene expression? Why is regulation of gene expression important for normal…
The continuity of life is based on heritable information in the form of DNA. Use the law of segregation and the law of independent assortment to explain how the passage of genes from parents to offspring (as alleles) ensures the perpetuation of parental traits in offspring and genetic variation among offspring. Describe briefly how Mendel demonstrated each of these laws.

However, we now know that many (if not most) traits are not actually inherited according to these rules.
