- What does recessive mean?
- What does dominant mean?
- a A trait is hidden unless the genotype is homozygous recessive such as a tt
- b The trait is visible whenever a dominant allele is present in the genotype such as TT or Tt(both tall)
- c Situation in which the phenotypes produced by both alleles are completely expressed
- d the likelihood that a particular event will occur
- e The scientific study of heredity
5 Multiple choice questions
- They produce hundreds of offspring.
- When gametes are made, the alleles for each trait seperate from each other. That way each gamete carries only one allele for each gene.
- They predict the traits of the offspring of the genetic crosses.
- Traits can be controlled by incomplete alleles and codominant alleles, or by genes with more than two possible alleles. Traits can also be controlled by several genes.
- Each chromosome pairs with its corresponding homologous chromosome to form a tetrad.
5 True/False questions
Metaphase I → Spindle fibers attach to the chromosomes
Segregation → separation of alleles
What happens during each phase of Meiosis II? → During prophase, the chromosomes become visible. During metaphase, the chromosomes line up in the middle of the cell. During anaphase, the chromatids seperate. During telophase and cytokinesis, four new haploid cells are formed.
How many alleles per trait would there be in a gamete in a pea plant? → There is only one allele for a particular trait.
Polygenic traits → The scientific study of heredity
