Students will be able to
- define the terms chromosome, gene, and allele,
- explain what is meant by dominant and recessive alleles,
- understand that some alleles, such as those that control blood groups in humans, can be codominant,
- recognize when alleles for a gene are homozygous or heterozygous,
- understand that a genotype is all the genes of an organism, and the interaction of these genes is expressed in the phenotype.
