Study Notes
Cell Division and Gametogenesis
- Meiosis is the process that produces gametes (sperm and egg) in sexually reproducing organisms.
- Centromeres are specialized structures that hold sister chromatids together during cell division.
- Homologous chromosomes consist of two chromosomes carrying the same genes at the same loci.
- Apoptosis refers to programmed cell death as part of normal development or response to injury.
Cellular Mechanisms
- Centrioles are specialized structures in animal cell cytoplasm that organize and separate chromosomes during cell division.
- Mitosis results in two daughter cells with the same number of chromosomes as the parent cell.
- Sister chromatids are two copies of a chromosome joined together by a centromere.
Gametogenesis and Gender Differences
- Oogenesis is the process by which female gametes are produced, and it can involve complications more prominently experienced by females.
- Spermatogenesis is the process for male sperm cell development.
Genetic Processes
- Crossing over occurs during meiosis, allowing the exchange of genetic material between homologous chromosomes.
- Random distribution of chromosomes is ensured during meiosis, contributing to genetic diversity.
- Telomeres protect chromosome ends, and they shorten with each cell division in normal cells.
Reproductive Strategies
- Sexual reproduction involves the fusion of gametes from two parents.
- Asexual reproduction produces offspring without gametes, typically through processes like binary fission.
Genetic Inheritance
- The offspring from breeding two true-breeding parents demonstrates specific phenotypes and genotypes.
- Homozygous refers to individuals with two copies of the same allele, while recessive traits appear only with two recessive alleles.
Evolutionary Concepts
- Genetic drift can lead to reduced genetic variation within populations.
- Hardy-Weinberg equilibrium predicts that allele frequencies in a population remain constant without evolutionary influences.
- Natural selection drives evolution by leading to changes in allele frequencies over time.
Fossil and Population Studies
- Radiometric dating methods are used to determine the age of fossils.
- The phenomenon of pesticide resistance highlights evolution in real time.
Differences in Cell Division
- Major differences between mitosis and meiosis include the number of daughter cells produced (two vs. four) and the maintenance (mitosis) or halving (meiosis) of chromosome numbers.
- Meiosis I and II have distinct functions: meiosis I includes crossing over, while meiosis II is similar to mitosis.
Genotype and Phenotype
- The genotype refers to the genetic makeup, while phenotype is the observable characteristics.
- Genetic crosses yield specific ratios of genotypes and phenotypes among offspring.
Blood Types and Genetics
- Blood type O is known as the universal donor, while blood type AB is the universal recipient.
- Antigens and Rh factors, critical for blood transfusions, determine compatibility between donor and recipient blood types.
Mutations and Natural Selection
- Mutations provide genetic variation, which is essential for natural selection, enabling beneficial traits to become more common in a population.
- Evolution represents the overall change and adaptation of organisms over time, driven by mechanisms such as natural selection.
