Exam #5
Review
1. Review the vocabulary for most common terms used in genetics:
Gene, locus, allele, chromosome, gamete, hybrid, homozygous condition,
heterozygous condition, homozygous dominant, homozygous recessive individuals,
genotype, phenotype, homologous chromosomes, monohybrid cross, dihybrid cross.
2. Review Mendel’s insight into inheritance patterns:
3. Study the Theory of Segregation, phenotypic and genotypic ratios of monohybrid
cross
4. Study Mendel’s Theory of Independent Assortment, phenotypic and genotypic
ratios of dihybrid cross
5. ABO blood types: review the possible allelic combinations for ABO blood typing.
For blood type A – AA, or Ai
For blood type B – BB or Bi
For blood type AB – AB
For blood type O – ii
6. Incomplete dominance: F2 phenotypic ratio for incomplete dominance
7. Genes and the Environment: Study the examples of the environmental effect on
the phenotype
8. Review the Chromosomal basis of Inheritance:
Vocabulary-sex chromosomes, autosomes, karyotype, SRY gene
9. Study the standard symbols used in pedigrees
10. Review the Autosomal Dominant and Recessive Inheritance, examples.
11. Review the X-linked Recessive Inheritance: colorblindness, hemophilia
12. Distinguish between different types of mutation: duplication, inversion,
translocation, deletion, and changes in the number of chromosomes: aneuploidy,
polyploidy, nondisjunction, trisomy
13. Examples of female and male sex chromosome abnormalities
