- What does dominant mean?
- How many alleles for a particular trait do pea plants inherit from each parent?
- a The trait is visible whenever a dominant allele is present in the genotype such as TT or Tt(both tall)
- b Punnett squares use probability to predict the combinations of alleles in a genetic cross.
- c There is only one allele for a particular trait.
- d specific characteristic of an individual

5 Multiple choice questions
- meiosis I results in two haploid daugther cells, each with half the number of chromosomes as the original cell
- The diploid cells of most adult organisms contain two complete sets of inherited chromosomes and so two complete sets of genes.
- An individual's unique characteristics are determined by factors that are passed from parent to offspring.
- A polygenic trait is a trait that is contolled by two or more genes and produce a wide range of possible phenotypes.
5 True/False questions
Genotype → the genetic makeup of an organism
Example of a phenotype in pea plants and list the genotype → 50% tall and short; TT, Tt, tt; Pea plant height may be either tall or short.
Crossing-over → Situation in which the phenotypes produced by both alleles are completely expressed
Probability → the likelihood that a particular event will occur
Codominance → the genetic makeup of an organism
