Study Notes
Genetics and Heredity
- Genetics is the science of heredity and variation, studying the differences and similarities between parents and offspring.
- Heredity is the process that brings about these differences and similarities, resulting in the sum of qualities genetically derived from one's parents.
Vocabulary
- Allele: one of a pair of genes that occupy the same location on homologous chromosomes, affecting the same trait in animals.
- Cytoplasm: a complex solution of organic and inorganic components outside the cell nucleus, contained by a cell membrane.
- Diploid: refers to paired chromosomes in body cells.
- Gametes: male or female reproductive cells.
- Genes: the smallest unit of inheritance, a portion of a DNA molecule that occurs in pairs on chromosomes in the nucleus of every cell.
- Haploid: refers to the number of chromosomes in a sex cell, which is half of the original number.
- Heritability: the proportion of observed variation in a particular trait that can be inherited due to genetic factors.
- Nucleus: essential to cell functions, containing nuclear sap, and the source of chromosomes.
- Chromatin: forms colored bodies.
Cell Division and Reproduction
- Meiosis: cell division resulting in haploid cells.
- Mitosis: cell division of the nucleus of a somatic cell, resulting in two identical daughter nuclei in two cells.
- Oogenesis: meiosis in females.
- Spermatogenesis: meiosis in males.
Chromosomes
- X Chromosome: a female chromosome.
- Y Chromosome: a male chromosome.
