Essential knowledge 3.A.3: The chromosomal basis of inheritance provides an understanding of the pattern of passage (transmission) of genes from parent to offspring.
a. Rules of probability can be applied to analyze passage of single gene traits from parent to offspring.
b. Segregation and independent assortment of chromosomes result in genetic variation.
Evidence of student learning is a demonstrated understanding of each of the following:
1. Segregation and independent assortment can be applied to genes that are on different chromosomes.
2. Genes that are adjacent and close to each other on the same chromosome tend to move as a unit; the probability that they will segregate as a unit is a function of the distance between them.
3. The pattern of inheritance (monohybrid, dihybrid, sex-linked, and genes linked on the same homologous chromosome) can often be predicted from data that gives the parent genotype/ phenotype and/or the offspring phenotypes/genotypes.
c. Certain human genetic disorders can be attributed to the
inheritance of single gene traits or specific chromosomal changes, such as nondisjunction.
To foster student understanding of this concept, instructors can choose an illustrative example such as:
• Sickle cell anemia
• Tay-Sachs disease
• Huntington’s disease
• X-linked color blindness
• Trisomy 21/Down syndrome
• Klinefelter’s syndrome
d. Many ethical, social and medical issues surround human genetic disorders.
To foster student understanding of this concept, instructors can choose an illustrative example such as:
• Reproduction issues
• Civic issues such as ownership of genetic information, privacy, historical contexts, etc.
