Study Notes
Genetic Vocabulary - Chapter 12
- Section 12.2: Sex-linked genes are genes located on the sex chromosomes, often the X chromosome, and X-linked genes are specifically on the X chromosome.
Linked Genes and Genetic Recombination
- Section 12.3: Linked genes are genes situated close together on the same chromosome, meaning they tend to be inherited together during meiosis.
- Genetic recombination is the process where new combinations of genes arise in offspring, often through crossing over during meiosis. Parental types are the original combinations of alleles, while recombinant types are the new combinations.
- Crossing over is a significant event in meiosis, where homologous chromosomes exchange genetic material.
- A genetic map shows the relative positions of genes along a chromosome.
- A chi-square test is a statistical method used to determine if observed results differ significantly from expected results.
- A linkage map is a map of genes based on their physical proximity to each other on a chromosome, and the map units measure the distances between genes.
Chromosomal Aberrations
- Section 12.4: Nondisjunction is the failure of chromosomes to separate properly during meiosis, potentially leading to abnormal chromosome numbers in gametes and offspring.
- Aneuploidy is a condition characterized by an abnormal number of chromosomes, differing from the typical diploid number. Specific types include:
- Monosomic: one copy of a chromosome
- Trisomic: three copies of a chromosome
- Polyploidy: more than two complete sets of chromosomes.
- Deletion, duplication, inversion, and translocation are chromosomal aberrations that involve changes in chromosome structure.
