inheritance?
2. Define trait, loci, gene, allele.
3. Describe Mendel’s particulate hypothesis of inheritance.
4. What does it mean to be true-breeding?
5. What characteristics make pea plants ideal organisms for genetic studies?
6. Differentiate between homozygous and heterozygous genotypes.
7. How many alleles does it take to show a dominant trait?
8. Be able to conduct monohybrid crosses and determine genotypic and phenotypic
ratios.
9. How are testcrosses used to determine unknown genotypes?
10. Be able to analyze a pedigree and explain how traits are passed.
11. Do harmful disorder have to be recessive?
